■
When it selects the step angle, the driving current is selected, and stops the
current is selected, set by combining rotary switch (RSW) and mode change
switch (PSW).
1. Step angle select(S.S)
The divisions of the basic step angle (0.9
be set with this rotary switch.
Ex-factory setting is at 1 (division 2)
* The step angle select switch (S.S) and the number of partitions become invalid by EXT input signal ON
2. Driving current select(RUN)
The Motor operation current value can be selected with this rotary switch.
Ex-factory setting is at 0 (rated value).
* When there is a sufficient extra motor torque, lowering the operation current value will be effective in
3. Current Select when Stop (STP)
The motor current value when stop and when power down input signal ON
(power low function is selected by dip switch) can be selected with this rotary
switch.
Ex-factory setting is set at A (50%).
* The current setting when stop by STP becomes valid when the Motor stops (approximately 200ms after
The slave bureau address of serial communications is set with this rotary
switch.
Ex-factory setting is set at 0
* The slave station address of the pulse stream I/F mode is fixed at 0.
