Signal interface
Note
Alls signals are PELV (protected extra low voltage) signals as defined in
VDE 0160.
Signal interface input
GATE_N (enable/disable the clock signal). ENABLE_N (enables the
amplifier). For a signal description, see chapter 4.
24 V standard PLC optocoupler input:
U
high, min
= 15 V I
high, min
= 2 mA
U
high, max
= 30 V I
high, max
= 15 mA
U
low, max
= 5 V I
low, max
= 0.2 mA Input open corresponds
U
low, min
= -3 V I
low, min
= -15 mA to low signal.
Max. transient overvoltage 35 V/500 ms
Signal interface outputs
READY2 (readiness), ZERO (ring counter zero signal), MSTILL (Motor
standstill). For a signal description, see chapter 4.
