If the response of the torque limitation operation is slow, increase the gain, and if hunting occurs,
decrease the gain.
• Overload Stop Function Integral time (J91)
If the response of the torque limitation operation is slow, decrease the integral time, and if hunting
occurs, increase the integral time.
•
Overload Stop Function Current level (J92)
This function is used to correct the current command during current limitation. When the set value is
increased, the retention torque increases, but an inverter overload alarm (0LU) or a motor overload
alarm (0L1) may occur, and vibrations may occur in the mechanical system.

Battery Operation Enable Command (BATRY)
When the BATRY terminal is turned ON, undervoltage protection is disabled, and the motor can be
operated even in an undervoltage state. In an event that an elevator fails to stop at a normal position
due to power failure, this command is expected to operate the elevator to the normal position with a
low-voltage and small-capacity emergency power supply
.
When “BATR
Y” is allocated to the input terminal, the momentary power failure operation is not per-
formed regardless of the setting of Power Interruption Restart Mode Selection (F14), and the inverter
trips during a power failure.
When the BATRY terminal is ON, the input phase loss protection is disabled regardless of the setting
of Input Phase Loss Protection Function Selection (H411).
While the BATRY terminal is ON, the IRDY terminal turns OFF.

Universal Terminal
• The input terminal is not used as startup of the inverter functions, but it can be used as a signal
monitor.
• The inverter status is not output; the value set to parameters can be output from output terminals
[DO1], [DO2] and [ROA, ROB].
Universal DI
When “25:U-DI (Universal DI)” is allocated to the input terminal, ON/OFF can be checked by Operation
command (S06) and the input signal can be checked by Input Terminal Monitor (W40) regardless of
inverter operation.
