Positioning command
Positioning points: 64 points as standard, 512 points at maximum (up to 768 points
for the network connection specifications)
The positioning points vary depending on the PIO pattern selection and parameter.
Backup memory
Position number data and parameters are stored in the nonvolatile memory.
Serial EEPROM life: Approx. 100,000 times of rewriting
PIO interface 24 VDC isolation, dedicated 16-point inputs/16-point outputs
PIO interface power supply 24 VDC ±10% (external supply)
LED indicator
SV (green) --- Whether or not the servo is on / ALM (red) --- Whether or not an
alarm is present.
Serial communication RS485, 1 channel (conforming to the Modbus protocol)
Encoder interface Incremental specification conforming to EIA RS-422A/423A
Forced release of electromagnetic brake NOM/BK_RLS switch (front panel)

(Note 1) Rush current of 5 to 12 times the rated current is conducted for approximately 1 to 2 msec after turning the supply
on. Note that the rush current value varies depending on the impedance of the power line.
(Note 2) The maximum current is conducted at the servo motor exciting phase detection performed in the first servo on
processing after turning the power on (normally: approximately 1 to 2 seconds, maximum: 10 seconds).
* Select power supply of +24 VDC power supply of the “peak load support" specification or with sufficient capacity.
