*1 Set "1: Voltage-output/open-collector type" in "[Pr.89] Manual pulse generator/Incremental synchronous encoder input type selection" if
the manual pulse generator/Incremental synchronous encoder of voltage-output/open-collector type is used.
The default value is "1: Voltage-output/open-collector type".
*2 Set the signal input form in "[Pr.24] Manual pulse generator/Incremental synchronous encoder input selection".
*3 The 5 V DC power supply from the Simple Motion module must not be used if a separate power supply is applied to the manual pulse
generator/Incremental synchronous encoder. If a separate power supply is used, use a stabilized power supply of voltage 5 V DC.
Anything else may cause a failure.
Wiring example for manual pulse generator/incremental synchronous encoder
Wire the manual pulse generator/incremental synchronous encoder of differential output type and voltage output type/open-
collector type as follows.
Switch the input type of RD77MS by "[Pr.89] Manual pulse generator/Incremental synchronous encoder input type selection".
It is recommended to use the external 5 V power supply (5 V DC±5%) for the power supply of the manual pulse generator/
incremental synchronous encoder. When using the external power supply, do not connect with the 5 V terminal of RD77MS.
When using the internal power supply, connect the 5 V terminal of RD77MS and the 5 V (+) of the manual pulse generator/
incremental synchronous encoder.
In either case, connect the 0 V (-) of the manual pulse generator/incremental synchronous encoder and the SG of RD77MS.
Do not use the 5 V terminal of RD77MS except for connecting the manual pulse generator/incremental synchronous encoder.
It may cause a failure. Also, do not connect the manual pulse generator/incremental synchronous encoder whose current
consumption exceeds 200 mA.
