Overtorque (OTQ)
• This function outputs a signal when detecting a motor output torque estimated value exceeding a
specified level.
• Enabled when "overtorque signal" is selected in the multi-function output selection. You can use
this function only when "sensorless vector control", "0-Hz sensorless vector control", or "sensor
vector control" is selected in V/f characteristics selection A044/A244. With other settings, the
output is unstable.
• For elevating machines, use this signal for releasing the brake. To close the brake, use the
frequency arrival signal.
