Sensor ON Input This performs serial transmission of
multi-rotation data of the absolute
encoder and also outputs 1-rotation data
as the initial incremental pulses.
This input is enabled by setting the
Operation Switch when Using Absolute
Encoder (Pn015) to 0 or 2.
√√√
13 SENGND Signal ground This is a sensor ON signal ground.
42 BAT Backup battery input These are the backup battery
connection terminals used when the
absolute encoder power is interrupted.
(Connection to this terminal is not
necessary if you use the absolute
encoder battery cable for backup.)

Speed command input This is an analog input terminal for
speed command.
Use the Speed Command Scale
(Pn302) to change the rotation speed
scale for the command input.

Provides a torque command input (set
value: 0 or 2) according to the setting of
Torque Command/Speed Limit
Selection (Pn317).
Use the Torque Command Scale
(Pn319) to change the rotation speed
scale for the command input.
