Note: 1. The output mode is selected by the value of P.151. When P.151 is 0, then there is no output.
When P.151 is 1, then the voltage of output DC voltage of P.152 is the keep torque.
2. Suppose that P.152 = 6%, then the output voltage of zero speed is 6% of base frequency
voltage P.19.
3. This function is valid only at V/F, close-loop V/F control system, and close-loop vector control
mode. For more details, please refer to the motor control mode parameter P.300 and the
feedback control parameter P.350~P.354.
4. When P.151=1, the zero-speed running is carried out in close-loop vector control mode, DC
voltage breaking is carried out in V/F
close-loop control mode.

P.260)
P.155 “Over torque detection level”
P.156 “Over torque detection time
P.260 “Over torque detection selection”
