20 Using the SINAMICS function blocks 5 Using the SINAMICS function blocks 5.1 Enabling and stopping the Axis The axis is switched on using input bit "EnableAxis" = 1. OFF2 and OFF3 are preassigned 1 using input "ConfigEPos" and do not have to be written to for operation. The axis is ready to start when there is no error "AxisError"= "0" and no switching on inhibited "Lockout" = "0". Feedback signal "AxisIEnabled" goes to "1" after switching "EnableAxis". The "ModePos" input is decisive for the mode selection. The required operating mode is selected via this input. A simultaneous, multiple mode selection is therefore not possible. However, it is possible to switch between various subordinate modes within the operating mode. The input signals "CancelTraversing" (reject traversing task) and "IntermediateStop" (intermediate stop) are relevant for all modes except for jog and must be set to "1" when using EPos. 1. If the "CancelTraversing" bit is set to "0" this results in a ramp stop with 100% of the set deceleration. The task data is rejected and the axis can be assigned a new task from standstill. A mode change is possible in this state. 2. If the "IntermediateStop" bit is set to "0" this results in a ramp stop of the axis with the currently valid acceleration values. The task data is NOT rejected so that the axis continues with the motion when the bit is set to "1". A mode change is possible at standstill. 5.2 Activating the Software position limits By default the SINA_POS library deactivates the function of the CMMT to monitor the Software position limits of the axis. Without this function it s possible to instruct the drive to move to a position which is beyond its reachable limit. To ensure a safe operation with Software limit monitoring, it is required to enable bit 2 on the "ConfigEPos" variable. Since bit 0 and bit 1 are already set, input variable "ConfigEPos" must be set to 16#0000_0007. Please pay attention that the required parameters in the Festo Automation Suite are also correct. These can be found in the Axis tab: Page 20 of 24 Application Note CMMT-AS-PN controlled by SINAPOS functions block with Siemens S controller 1.10

21 Using the SINAMICS function blocks 5.3 Monitoring the Actual speed Where the setpoint velocity is directly set as user units, the actual drive speed is displayed different in the SINA_POS function block. The variable "ActVelocity" is used, where the value is scaled from 0 to 100% with hex = 100%. The base value can be modified in the Festo Automation Suite, as described in part of this document. It can also be changed using PNU (which refers to this exact same parameter). 5.4 Modes of Operations The CMMT-PN with the SINA_POS function block supports the following modes of operation: ModePos 1: Relative Positioning ModePos 2: Absolute Positioning task ModePos 3: Not Supported ModePos 4: Referencing Reference point approach ModePos 5: Referencing - Set reference point ModePos 6: Traversing blocks (record mode) ModePos 7: Jog ModePos 8: Not Supported Relative Positioning 1. Requirements: - The mode is selected with "ModePos"=1. - The device is switched on via "EnableAxis" - The axis must be referenced - The axis is at standstill if selected by an operating mode greater than 3. A change within the operating modes (1,2) is possible at any time. 2. Sequence: The traversing path and dynamic responses are specified via the inputs "Position", "Velocity", "OverAcc" (acceleration override) and "OverDec" (deceleration override). The operating conditions "CancelTraversing" and "IntermediateStop" must be set to "1". "Jog1" and "Jog2" have no effect and should be set to "0" (false). The direction of travel in relative positioning always results from the sign of the traversing path. Traversing motion is started with a positive edge at "ExecuteMode". The block acknowledges when the end of the traversing path is reached successfully with "AxisPosOk". If an error occurs during the traversing motion, the output signal "Error" is issued. Note The current command can be replaced on-the-fly by a new command via "ExecuteMode". This is only possible for the "ModePos" 1 and 2.

22 Using the SINAMICS function blocks Absolute Positioning 1. Requirements: - The mode is selected with "ModePos"=2 - The device is switched on via "EnableAxis" - The axis must be referenced - The axis is at standstill if selected by an operating mode greater than 3. A change within the operating modes (1,2) is possible at any time. 2. Sequence: The traversing path and dynamic responses are specified via the inputs "Position", "Velocity", "OverAcc" (acceleration override) and "OverDec" (deceleration override). The operating conditions "CancelTraversing" and "IntermediateStop" must be set to "1". "Jog1" and "Jog2" have no effect and must be set to "0". Traversing motion is started with a positive edge at "ExecuteMode". The block acknowledges when the end of the traversing path is reached successfully with "AxisPosOk". If an error occurs during the traversing motion, the output signal "Error" is issued. Note The current command can be replaced on-the-fly by a new command via "ExecuteMode". This is only possible for the "ModePos" 1 and 2 Referencing - Reference point approach The Referencing reference point approach mode enables the reference point approach of the axis, selected in the Automation Suite. 1. Requirements: - The mode is selected with "ModePos"=4 - The device is switched on using "EnableAxis". - The axis is at standstill 2. Sequence: All required parameters for homing (homing mode, velocity, etc) are set in the Automation Suite. The reference point approach is started with a positive edge at "ExecuteMode". Output signal "AxisRef" is set if the reference point is appropriately found and evaluated. If an error occurs during traversing motion, the output signal "Error" is issued. Referencing Set reference point The Referencing set reference point mode enables the referencing of the axis at the current position. 1. Requirements: - The mode is selected with "ModePos"=5 - The axis can be in closed-loop control, but must be at a standstill. 2. Sequence: The axis is at standstill and the reference point is set with a positive edge at "ExecuteMode". If an error occurs while setting the reference point, the output signal "Error" is issued.

23 Using the SINAMICS function blocks Traversing blocks (record mode) The Traversing blocks mode is implemented via the "Traversing blocks" drive function. It enables the creation of automatic programs, velocity mode, force mode, travel to fixed stop and outputs to be set and reset. It uses the records that are created in the Record list tab in the Automation Suite. 1. Requirements: - The mode is selected with "ModePos"=6 - The device is switched on using "EnableAxis" - The axis is at standstill - The axis must be referenced 2. Sequence: The selection of the traversing task to be started is set via the "Position" input. The value refers to the record list and can be between 0 and 127. The operating conditions "CancelTraversing" and "IntermediateStop" must be set to "1". "Jog1" and "Jog2" have no effect and should be set to "0". Traversing motion is started with a positive edge at "ExecuteMode". The block displays the current command processing with "AxisEnabled" and acknowledges when the target position is reached successfully or the last task step completed with "AxisPosOk". If an error occurs during the traversing motion, the output signal "Error" is issued. Jog 1. Requirements: - The mode is selected with "ModePos" = 7. - The device is switched on using "EnableAxis" - The axis is at standstill 2. Sequence: "Jog1" and "Jog2" are the signal sources for the jog mode in EPos. The "ExecuteMode" signal is not required in this mode. "Jog1" = Positive "Jog2" = Negative The dynamic values for jogging are set in the Automation Suite on the Jog mode tab. The corresponding parameters are: - Velocity (slow) - Acceleration (slow) - Jerk (slow) Application Note CMMT-AS-PN controlled by SINAPOS functions block with Siemens S controller 1.10 Page 23 of 24

24 5.5 Diagnostic messages The function block can give multiple types of diagnostic messages. The following chapter will explain how to handle or solve them. Drive Error When the drive is in error, the output "ActFault" of the function block SINA_POS will provide a message number. This message number relates to the same number which is shown in the Festo Automation Suite. After elimination of the fault, the error must be acknowledged using the bit "AckError" before enabling the axis again. Drive Warning When the drive has a warning message, the output "ActWarning" will provide a message number. After elimination of the warning the message number will disappear. Function block faults When an error on the function block has been detected, the "Error" group error and the "ErrorId" are set. The following errors are monitored: Error number Status Cause Remedy 16#7002 No error -- 16#8600 Interruption of the communication to the SINAMICS drive: Error DPRD_DAT 16#8601 Interruption of the communication to the SINAMICS drive: Error DPWR_DAT Check the communication connections / settings (see DiagId) Check the communication connections / settings (see DiagId) 16#8202 Incorrect operating mode selected Set "ModePos" from 1 to 8 16#8203 Incorrect parameterization of the override inputs Check the settings of the override inputs 16#8204 Invalid traversing block number Enter a traversing block number from 0 to #8401 Alarm message(s) in the SINAMICS drive 16#8402 Switching on inhibited of the SINAMICS drive active 16#8403 Flying referencing could not be started Evaluation of the error code at the "ActFault" output Check whether axis/encoder is parked, safety functions active, Parameter p10 0 Check for pending alarms/faults in the drive, The following settings will help for text-transfer: Options Pasting within the same document Pasting between documents Pasting between documents when style definitions conflict Pasting from other programs Settings Keep Source Formatting Use Destination Styles Use Destination Styles Use Destination Styles Table 5.1: Word Options Page 24 of 24 Application Note CMMT-AS-PN controlled by SINAPOS functions block with Siemens S controller 1.10
