I would like to operate a fast exit thanks to a technological module. But in my configuration, I don't have my fast sotie, I only have profinet for the Siemens driver however, my fast output is well configured and on the documentation it is marked that it is possible to do it with the model of my PLC. I am on TIA V16. I use a driver like this (see photo) it's a TB6600 motor step driver; On the S7-1200 it works without problem but on the 1500, I can't, do you have any idea ? thank you so much !

Configure one of the pulse hardware interfaces as a PTO (note some crucial settings describing a stepper there). Then assign its IO addresses to the OB MC-Servo. Come back to the axis configuration. Drive interface set to Profinet, Drive and now you should be able to select the PTO as a drive for the axis.

For an expanded description look at the topic: 1511c-1pn-unable-to-configure-pto Focus especially to the post with date code 5/25/2018 4:50 PM. There is a sample attached there. For convenience sake the message text is quoted. Yu-wen Tang Dear Yuvaraj.T, The steps for configuring the S7-1511C-1PN PTO are as below: Select: PLC > Properties > Pulse generator > PTO1/PWM1 > General > Operating mode > PTO (pulse (A) and direction (B) ex. Set: PLC > Properties > Pulse generator > PTO1/PWM1 > Data exchange with axis (Make sure that the parameters for 'Data exchange with axis' and 'Fine resolution' correspond to the parameters in the configuration of the used technology object.) Set and note: PLC > Properties > Pulse generator > PTO1/PWM1 > Hardware inputs/outputs Add: Technology objects > Motion Control > TO_PositioningAxis Set: Technology objects > PositioningAxis_1 > Configuration > Hardware interface > Drive > Drive > Pulse_1 Set: Technology objects > PositioningAxis_1 > Configuration > Hardware interface > Data exchange with the drive (Make sure that the parameters correspond to the parameters of PLC > Properties > Pulse generator > PTO1/PWM1 > Data exchange with axis) Set: Technology objects > PositioningAxis_1 > Configuration > Hardware interface > Data exchange with encoder(Make sure that the parameters correspond to the parameters of PLC > Properties > Pulse generator > PTO1/PWM1 > Data exchange with axis) Set: Technology objects > PositioningAxis_1 > Configuration > Extended parameters Compile and download Test: Technology objects > PositioningAxis_1 > Commissioning (as normal) Program your MC commands (as normal) Demo project for configuration as attached (with simulated axis). Best regards, Yu-wen Regards.

The SIMATIC S7-1511C uses 24V output singals at PTO connectors. If you use this TB6600 motor step driver with a SIMATIC S7-1200, normally you use a "option board" for 5V singal outputs. This is not possible at the S7-1511C... Take care! For more information, see CPU manual: https://support.industry.siemens.com/cs/ww/en/view/109752843

Page 28: Stepper motors Drives with a stepper motor interface are connected using telegram 3 and with the help of PTO (Pulse Train Output) pulse generators. For functional support of stepper motor operation, quantization of the control deviation can be set. Through the specification of a quantization, a range around the target position is defined in which no correction of the actual position is to be made. This prevents a possible oscillation of the stepper motor around the target position. Two types of quantization can be set: ● Quantization of the control deviation corresponding to the encoder resolution ("<TO>.PositionControl.ControlDifferenceQuantization.Mode" = 1) This prevents oscillation of the stopped motor between two increment values, for example. This mode is especially helpful when using multiple encoders. With this setting, the quantization is adapted appropriately at an encoder switchover. This mode is helpful for stepper motors with encoders in which the resolution of the encoder is lower than the step size of the stepper motor. ● Direct specification of a value for quantization of the control deviation. ("<TO>.PositionControl.ControlDifferenceQuantization.Mode" = 2, value setting in "<TO>.PositionControl.ControlDifferenceQuantization.Value") This mode is helpful for stepper motors with encoders in which the resolution of the encoder is greater than the step size of the stepper motor. https://support.industry.siemens.com/cs/ww/en/view/109766462 5.3.5 TM PTO 4 (S7-1500, S7-1500T) https://support.industry.siemens.com/cs/ww/en/view/109766459
