JOG Command: JOG (Byte 2, Bit 3)
The DeviceNet Unit will start JOG operation when it detects the rising edge of the JOG
bit. JOG operation will continue while this bit is set to 1.
When the JOG bit is set to 0, the Servomotor will decelerate to a stop and the JOG oper-
ation will end. The direction for JOG is determined by the Movement Direction set in the
command data.
An override can be set for this command in the command data. However, it is clamped at
the maximum speed. The override can be from 0% to 200% of the parameter speed or a
specific speed can be set in the command data. Which method is used depends on Pn830
(JOG Unit Selection).

0: Positive direction, 1: Negative direction

When Pn830 = 1
Step Command: STEP (Byte 2, Bit 4)
The DeviceNet Unit will start step operation from the present position when it detects the
rising edge of the STEP bit. While the STEP bit is set to 1, the axis will travel only the
distance set in the specified parameter. If the STEP bit is set to 0 during step operation,
the Servomotor will decelerate to a stop and the step operation will end. The remaining
travel distance will be canceled.
The direction of movement for step operations is determined by the Movement Direction
set in the command data. The number of the step distance (0 to 3) is also set in the com-
mand data. The parameter data set in Pn844 to Pn847 will be used for the step distance.
Settings Data Area
Movement direction 0: Positive direction, 1: Negative direction
Command data
Set the selection number for step distance.
0: Uses Pn844 data.
1: Uses Pn845 data.
2: Uses Pn846 data.
3: Uses Pn847 data.
