y
Set up JOG speed in CR#10, #11.
y
X0 = On: JOG+ forward pulse output
y
X1 = On: JOG- reverse pulse output
y
X0, X1 = Off: stop the JOG operation.

Variable Speed Operation Mode
1.
Control requirements
y
Set up CR#25 for variable speed operation (+/- for the direction).
y
Write K16 (H’10, i.e. b4 = 1) to enable the variable speed operation mode.
2.
Devices
y
X0 = On/Off: enable/disable variable speed operation.
y
X1 = On: set up the variable speed as 50kHz.
y
X2 = On: set up the variable speed as 60kHz.
y
X3 = On: set up the variable speed as 70kHz.
