The α series servo amplifier has a terminal for the emergency stop signal
on the power supply module (connector: CX4). Always use the
emergency stop signal.
D When the contact is closed (on), the spindle motors and servo motors
can operate. When the contact is open (off), the external magnetic
contactor is turned off, preventing operation of the spindle motors and
servo motors.
D When the contact is opened (turned off) while a motor is rotating, a
spindle motor will decelerate naturally and stop, while a servo motor
will stop by the application of its dynamic brake.
D The contact input signal has the following specifications:
- External contact capacity: 30 VDC or higher, 100 mA or higher
- Significant levels for contactless input (voltage between input
terminals)
Low (logical 0) : 2 V or lower
High (logical 1) : 20 V or higher
