5 Enable_out_b
Control voltage 24 VDC
Controller type Compax3
Voltage range
21 - 27VDC
Current drain of the device
0.8 A
Total current drain
0.8 A + Total load of the digital outputs +
current for the motor holding brake
Ripple
0.5Vpp
Requirement according to safe extra
low voltage (SELV)
yes
Power stage enable: X4/3=24 VDC
Tolerance range: 18.0 V – 33.6 V / 720 Ω
The +24V supply can be taken, for example, from Pin 1.
Safe standstill (X4/3=0V)
For implementation of the "Safe standstill" safety feature in accordance with the
“protection against unexpected start-up“ described in EN1037. Please refer to the
respective chapter (in the paper version “Installation Manual Compax3) with the
respective circuitry examples!
The energy supply to the drive is reliably shut off, the motor has no torque.
A relay contact is located between X4/4 and X4/5 (normally closed contact)
Enable_out_a - Enable_out_b Power output
stage is
Contact opened activated
Contact closed deactivated
Series connection of these contacts permits certain determination of whether all
drives are de-energized.
Relay contact data:
Switching voltage (AC/DC): 100 mV – 60 V
Switching current: 10 mA – 0.3 A
