ONLY when the inverter is switched off and the volt-

age supply is disconnected may the feedback con-
nectors be removed or connected!
The second incremental encoder connection serves as a buffered output of
the motor encoder. This can be used by other control systems for speed or
position control. The output signals are according to the RS422 line driver
signal standard.

The internal 24VDC power supply has a maximum load capacity of 170mA.
The 5V supply has a maximum load capacity of 500mA. Both values
assume no loading on the supplies of connection X3A. If connections or
loads are placed on both terminals, the total load between the two must not
exceed these values.
The following specifications apply to encoder interface X3B, channel 2
• Max. operating frequency:
• External terminating resistance:
• RS422 level square wave
voltage level:
For proper noise immunity, the RS422 standard requires a termination
resistor to be placed at the device which is receiving the simulated
encoder signal. The resistors shall be connected from A+ to A-, B+ to
B-, N+ to N- (only when used).
