12.1-11-12

Reverse Speed Limit (Torque Mode)
Default: 10
Settings 0–120%
 These parameters define the speed limit in the forward and reverse directions in torque mode
(Pr.01-00 maximum operation frequency = 100%).
Zero Torque Command Mode Selection
Default: 0
Settings 0: Torque mode
1: Speed mode
 This parameter is only valid in TQCPG IM and TQCPG PM, and it defines the mode when the
speed limit is 0% or 0Hz.
 When you set Pr.11-39 to 0, and the speed limit is 0% or 0Hz, the motor generates an excitation
current, and the torque command Pr.11-34 limits the torque.
 When you set Pr.11-39 to 1, and the speed limit is 0% or 0Hz, the AC motor drive can generate
output torque through the speed controller (the torque limit is Pr.06-12), and the control mode
changes from TQC + PG to FOC + PG mode. The motor has a holding torque. If the speed
command is not 0, the drive automatically changes it to 0.
