Maximum voltage on input
1) Terminals X59-1 and X59-2 can be programmed as input, parameter 33-60.
2) Selected in parameter 5-00 Digital I/O mode.

Terminal number
Maximum load
The internal 24V power supply can be disconnected via parameter 33-85, an external 24V power
supply must then be connected to X58-1 and X58-2.
Encoder Inputs

Maximum cable length
1) Always observe specifications/limitations prescribed by the encoder supplier.
2) 150 m cable is possible up to 500 kHz clock frequency, above 500 kHz cable length must be
limited further.
