(28) Absolute Battery Voltage Low Warning (BALM) PLC Input Signal
With an absolute system, this signal is OFF when the absolute battery voltage is normal. It remains OFF
with an incremental system.
This BALM signal turns ON when the absolute battery voltage drops to 3.1 V. If the controller is operated
continuously and the voltage drops further to 2.5 V, the controller can no longer retain position information.
(If you are using an absolute system and this signal turns ON, replace the battery at the earliest
opportunity.)
(29) Vibration Damping Mode Selection 0, 1 (NTC0, NTC1) PLC Output Signals
The vibration damping control function suppresses the load vibration induced by IAI’s actuator. Measure
the vibration frequency and set it in a parameter. In another parameter, select and set an appropriate
option based on a combination of these signals.
For details, refer to the operation manual for your controller.

Input timing
An input timing chart of NTC0/NTC1 signals is shown below.
Caution: Since the statuses of NTC0/NTC1 signals are loaded when a movement command (DSTR) is
recognized, nothing happens when the NTC0/NTC1 signals are turned ON/OFF while the
actuator is moving.
