Note:
• Holds via an external source so that the torque compensation signal does not change during run. If the torque compensation signal is
changed during run, the motor may produce oscillation.
• When motor reverse is set to the increase command and motor forward is set to the decrease command, the polarity of the torque
compensation signal will reverse.
Analog Input FilterTime Constant
When setting b1-01 = 1 [Frequency Reference Selection 1 = Analog Input], noise is introduced into the analog
frequency reference during run. If the ride quality of the elevator worsens, take the following measures.

Enter the analog signal as the torque compensation (torque bias) signal in accordance with load amount
prior to running the drive up till drive operation completes. The default setting is 10 V/100% torque.
Enter a positive polarity during a motoring load, and enter a negative polarity during a regenerative
load.
In the same manner as an increase, enter the analog signal as the torque compensation (torque bias)
signal in accordance with load amount before running the drive up to when it finishes running. The
default setting is 10 V/100% torque.
Enter a negative polarity during a motoring load, and enter a positive polarity during a regenerative
load.
