Assignment of the analog inputs
● Terminal: -X2:50 ... 52:
– Apply the speed setpoint which is active in normal operation to these terminals.
– You can use the terminal 50 as current input or the terminal 52 as voltage input. The
terminal 51 is the ground connection.
– The input range from 0 mA to 20 mA or from 0 V to 10 V is proportional to the output
frequency from 0 Hz to 50 Hz.
● Terminal: -X2:53, 54:
– The signal for the speed actual value feedback can be supplied to this input. The
values 0 mA to 20 mA at terminal 53 and 0 V to 10 V or up to 180 V at terminal 54 are
preset.
– You can connect an analog motor tachometer to these terminals.
– More detailed information can be found in the section "DIL switches S1 and S2"
(Page 149).
– You can use the signal in the software for limit value comparisons or as display.
Assignment of the analog outputs
● Isolated terminal -X2:62, 63:
An output signal of 4 mA to 20 mA is present here. This corresponds to a motor current
from zero up to a unit-dependent value.
● Isolated terminal -X2:60, 61:
This output provides a speed signal. A value from 4 mA to 20 mA is the default. This
corresponds to a motor speed from zero to 1500 rpm.
● Option "Peripheral board 4":
The torque and power are available at terminals -X2:64 … 67. A value from 4 mA to 20
mA is the default. The corresponding countervalue is output-dependent and is stored in
the parameterization software "IMS".
Input "Mandatory mains power isolation" / PTC thermistor inputs on peripheral board
Detailed information can be found in the section "Peripheral boards 1 to 4" (Page 37).
