1.4.1.3 Signal connection of signal interface 1
Signal levels of the inputs correspond to the RS
422 interface; there is no electrical separation of
the inputs and outputs from the motor voltage. The
earth (GND) is connected internally to the protec-
tive conductor.
Inputs:
•
Low-level -0.1 V to -30 V
•
High-level 0.1 V to 30 V
READY output: Open Collector (npn)

max
10 mA
short-circuit proof up to 6 V DC
Pin 6 and 14 (+,- READY) are connected in parallel
with signal interface 2.
1.4.1.4 Signal connection of signal interface 2
Signal levels are designed for driving by PLC
standard signals; there is no electrical separation
of the inputs and outputs from the motor voltage.
The earth (GND) is connected internally to the
protective conductor.
