(including ripple):

(including ripple):
10 V to 30 V
The external supply is required for the following digital outputs:
8 outputs of the drive–specific terminals (X461, O0.A – O3.A/X462, O0.B – O3.B)
8 outputs of the optional TERMINAL module (X432, O4 – O11)
When dimensioning the external power supply, the total current of all of the digital outputs must
be taken into account.
Maximum total current:
for the control board (all 8 outputs):
2.4 A
for the optional TERMINAL module (all 8 outputs):
480 mA

Enable voltage
(+24 V)
S
Reference:
Terminal 19
Maximum current (for the total group): 500 mA
Note:
The enable voltage (terminal 9) can be used to supply
the enable signals (e.g. pulse enable) as 24 V auxil-
iary voltage.

Pulse enable
(+24 V)
I
Voltage tolerance
(including ripple):
21 V to 30 V
Typ. curr. consumption: 25 mA at 24 V
Note:
The pulse enable acts simultaneously on drive A and
drive B. When this pulse enable is withdrawn, the
drives ”coast down” unbraked.

(Reference for all
digital inputs)
S
Note:
If the enable signals are to be controlled from an exter-
nal voltage and not from terminal 9, then the reference
potential (ground) of the external source must be con-
nected to this terminal.
