HT[N] – Holding torque

Purpose:

This command applies to the motor current in open loop stepping mode (UM=3)

HT[1] defines the holding torque, in Amperes.
HT[2] defines the torque addition due to speed, Amp/(Count/Sec)
HT[3] defines the torque addition due to acceleration, Amp/(Count/Sec

2

)

HT[2] and HT[3] are defined differently for open loop and closed loop stepper

control (see PN[9]).

• For open loop mode, HT[2] and HT[3] are defined for PN[4] counts/electrical

rev. or PN[4]xS/4 counts/mechanical rev., where S is the number of steps.

• For closed loop mode, HT[2] and HT[3] are defined for the encoder counts.
