Explanation of the role of TD in the stepper drive module
Explanation of the function of TD in the stepper drive module
- What is the primary function of TD in the Dip SW settings of the Motionnet STP stepper drive module?
– As shown in the diagram below:

- What is the primary function of TD in the Dip SW settings of the stepper drive module?
– TD is the Watch-dog option, and the default value is off
– It is mainly used for configuring the response of the stepper drive module when communication is lost:
– When TD is set to Off (the default, which is an active state), if communication is interrupted, the stepper drive module will complete the motion command that was in progress before the communication interruption and then stop
– When TD is set to ON, if communication is lost, the stepper drive module will immediately stop along with the communication interruption
- Those Motionnet stepper drive models support this feature:
– STP-M111A
– STP-M112A
– STP-M510A
– STP-M511A
– STP-M512A
