DIGIVEX Little Drive Servoamplifier

1.3.3.6 logic outputs

Speed detection
The OUT1 output status acts in the following manner:
Speed < Threshold (OUT1)
Speed > Threshold (OUT1)
NB: 19 rpm ≤ threshold (OUT1) ≤ 100,000 rpm
Speed reached
OUT2 output changes to 1 status when the motor speed is within the range given by + or -
the Threshold (OUT2) value:
± Limit (OUT2)
(input instruction – threshold (OUT2) < actual speed < input instruction + threshold (OUT2)

1.3.3.7 Brake action

The drive can be declared in the parameters with a brake function.
The 24 V brake supply (terminal block B1) is monitored by the drive.
24 V present: Axis under torque. Removal of limitation of 90% of rated motor current.
24 V absent: Axis at reduced torque with 90% of rated motor current.
The brake engage or release order is in no event given by the drive but by the external control.
The control can monitor the drive outputs indicating zero speed to decide whether or not to apply
the brake.
