ServoWire Motion & Logic Controller Manual System Power Wiring & Interlocks
Emergency ‐ Stop / Quick ‐ Stop and Drive Ready Configuration
Located on the ServoWire drive is an Emergency ‐ Stop / Quick ‐ Stop input and Drive Ready output,
allowing fail ‐ safe control.
Emergency Stop Input:
A discrete input can be configured to operate as Emergency Stop input. When unasserted, this input
causes the servo drive to generate a drive fault and disable output power to the motor, as well as
generating an OP_FAULT condition in the application program.
Quick Stop Input:
A discrete input can be configured to operate as Quick Stop input. Un ‐ asserting the input in this mode
generates an OP_ALARM condition in the application program and has the effects indicated below,
which are dependent on the axis mode of operation (torque, velocity or position).
Torque mode ‐ Generates an OP_ALARM condition in the application program, output remains
enabled and the drive continues to receive torque commands. This allows the application
program to decelerate the load under control.
Velocity / Position mode ‐ Generates an OP_ALARM condition in the application program,
output remains enabled, and zero speed is commanded. Commanding zero speed may result in
commanded current to bring the motor to a stop.
WARNING: The SMLC and servo drives must be configured in ServoWire Pro for E ‐ Stop /
Quick ‐ Stop operation. Refer to the ServoWire Pro online documentation for more
information .
