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.
