Installation
Warning! Follow the safety instructions given in this guide and in
the drive’s hardware manual.
Setting the supply voltage
Warning! Selecting the wrong supply voltage may damage or
break the encoder.
Two supply voltages are available on pins 4 and 5 in connector
X81. Only one of them can be used to supply an encoder. The
supply voltage is selected by placing a jumper on connector X81
as described in the figure below. The following supply voltages
can be selected:
• +15 V DC ± 20% 200mA (max.)
• +24 V DC ± 20% 200mA (max.)
You can also connect an external 10 - 24 V DC power supply to
pins 4 and 5 in connector X81. In that case, the jumper must be
removed.
