POINT
In this configuration, only the STO function is supported. The forced stop
deceleration function is not available.
(a) 200 V class
POINT
When using the servo amplifier of 7 kW or less, make sure to disconnect the
wiring of built-in regenerative resistor (5 kW or less: P+ and D, 7 kW: P+ and C).
