  • Page 21 • A separate digital output from the safety relay is connected to a general digital input of the Vacon 100 drive. The general digital input must be programmed to execute the drive stop command and initiates the drive stop function without a time delay (must be set to "stop by ramp") and causes motor deceleration.
