Relay 2
Relay no. 2, contacts X4.5 and X4.6
Brake
Relay for holding brake or frequency converter start, terminal X2.2
PWM
PWM signal for analog output, terminal X2.4
WDog
Watchdog/Charge-Pump-Signal, switches all outputs free
Unlike inputs, output signals cannot be inverted (active low/hi) because otherwise the safe off state would not be defined. For
the function of all other outputs the charge pump signal must be assigned to pin "WDog". Otherwise all outputs, including the step
signals, are disabled.
When using stepper motor output stages, the current reduction signal must be applied to the enable pin if they have a current
reduction input. This is always active when all drives are stopped. Attention: When using leadshine or similar power amplifiers,
the current reduction signal must
not
be assigned. When using servos, however, the servo enable signal must be assigned to the
enable pin. This is active when the drives are moving.
The relays can be assigned to any other output signals. Examples:
Standard assignment: Relay 1 = spindle forward, relay 2 = coolant, brake = holding brake
no brake, FU, add. spray cooling: relay1 = coolant, relay2 = spray cooling, brake = spindle forward
Spindle with right/left rotation: relay1 = spindle forward, relay2 = spindle reverse
If the number of available outputs or inputs is not sufficient for the application, they can be increased with an expansion
module.
