(AWG: 24 ... 12)
Control voltage 24VDC Compax3S and Compax3H
Controller type
Compax3
Voltage range
21 - 27VDC
Mains module
with switch-on current limitation, due to
capacitive load
Fuse
MTP miniature circuit breaker or "delayed action
fuse", due to capacitive load
Current drain of the device
0.8A
Total current drain
0.8 A + Total load of the digital o
current for the motor holding brake
Ripple
0.5Vpp
Requirement according to safe extra
low voltage (SELV)
yes
Short-circuit proof
conditional (internally protected with 3.15AT)
Hardware - enable (input X4/3 = 24VDC)
This input is used as safety interrupt for the power output stage.
Tolerance range: 18.0V - 33.6V / 720
Ω
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. Observe
instructions in the corresponding
section
(see page 68) with the 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
disabled
Series connection of these contacts permits certain determination of whether all
drives are de-energized.
Relay contact data:
Switching voltage (AC/DC): 100mV -60V
Switching current: 10mA - 0.3A
Switching power: 1mW...7W
