Level WE Technical data, description
Supply voltages
h Setpoint voltage output +10 V H – Supply voltage for external setpoint potentiometer.
Load carrying capacity: 20 mA
Reference potential: Terminal L
P24 Control voltage output
+24 V H – Supply voltage for actuation of digital inputs 1 to 8
and FW.
Load carrying capacity: 100 mA
Reference potential: Terminal CM1
Reference potentials
CM1 Reference potential 0 V – Reference potential terminals 1 to 8, FM, FW,
TH and P24
CM2 External control voltage
input
Up to 27 V – Connection: reference potential (0 V) of the external
voltage source for the transistor outputs, terminals
11 to 15.
Load carrying capacity: Up to 250 mA
(sum of terminals 11 to 15)
L Reference potential
0 V – Reference potential, terminals AM, AMI, H, O,
OI and O2
PLC Common connection,
terminals 1 to 8 and FW
By default, the frequency inverters are supplied with a link between PLC and CM1, so that the potential on terminal
PLC – and therefore on the digital inputs that are not energized – is 0 V (negative logic). If PLC is applied to P24,
the control logic is positive.
Digital inputs
1 Digital input HIGH = +12 to +27 V
LOW = 0 to +3 V
RST = reset PNP logic, configurable, R
