Switch

1. Pulse Input Setting Switch(SW1)

Indication	Switch Name	Function
2P/1P	Selecting pulse input mode	Selectable 1-Pulse input mode or 2-Pulse input mode as Pulse input signal. ON: 1-Pulse mode OFF: 2-Pulse mode ※ Default: 2-Pulse mode

2. Resolution Setting Switch(SW3)

The Number of pulse per revolution.

Position	Pulse/Revolution
0	500^*1
1	500
2	1,000
3	1,600
4	2,000

Position	Pulse/Revolution
5	3,600
6	5,000
7	6,400
8	7,200
9	10,000^*2

* 1 : Resolution of position “0” will be different according to the resolution of encoder adopted to the product.
But in case of the encoder with 10,000[ppr] resolution, it will be set as 500.
※ Selected resolution is more then encoder resolution, motor shall be operated by microstep between pulses.
