7.10 Grounding system
AGND
ground for analog inputs and outputs, internal analog ground
DGND
ground for digital inputs and outputs ( X3), optically isolated
XGND
ground for 24V aux. supply (X4)
EGND
ground for encoder-emulation, RS232, digital In-and outputs (X10); power supply PMCprimo
Drive2 and master encoder, optically and inductively isolated
The potential isolation is shown in the block diagram (⇒ S. 17/18).
7.11 Control for motor-holding brake
A 24V / max. 2A holding brake in the motor can be controlled directly by the PMCprimo Drive2.
This function does not ensure personnel safety! (s. Option –AS- page 28)
The brake function must be enabled through the setup software PDRIVE with the parameter
„brake“.
In the diagram below you can see the time and functional relationships between the ENABLE
signal, speed setpoint, speed and braking force.
