AC90 TENSION CONTROL FREQUENCY INVERTER MANUAL
Torque control FWD upper frequency limit No set: It sets FWD speed limit under torque control.
Torque control FWD upper frequency limit bias: It adjusts FWD speed limit. After bias, FWD frequency under torque
control is.
FWD frequency under torque control= Torque control FWD upper frequency limit No set+(max frequency*
Torque control FWD upper frequency limit bias)
Torque control REV upper

frequency limit No set
Torque control REV upper

frequency limit bias
Torque control REV upper frequency limit No set: It sets REV speed limit under torque control.
Torque control REV upper frequency limit bias: It adjusts REV speed limit. After bias, FWD frequency under torque
control is.
REV frequency under torque control= Torque control REV upper frequency limit No set+(max frequency
Torque control REV upper frequency limit bias)
Upper frequency limit under
F7.28
small torque
Upper frequency limit under small torque: It sets max output frequency under small torque output to keep stable
speed.
Small torque value
F7.29
threshold
Small torque value threshold: While give torque is smaller than this value, the inverter output frequency upper limit is
[F7.28]. It is main function is to keep stable speed under certain small torque.
While it is "0",inverter close this function and stop output. The motor is in free state.
