Jog
At its default setting, when you press this key, the motor
jogs at a speed determined by the [Jog Vel] parameter for
any axis that is enabled (default is 20% of motor rated
speed). Releasing the key stops the function. You can use
this function during startup as a battery box to move an
axis. To change this function, you need to reconfigure the
[Command Mask] and [Typ 1 Logic Axis] parameters.
Refer to the Configuring Your 1394 Analog Servo System
chapter for more information.
To jog for the axis:
1. Supply a 24V DC enable signal to the axis that is in
JOG mode.
2. Press STOP on the HIM to have control of the velocity
reference command.
3. Press JOG for the axis to jog at the value set in the
[Jog Vel] parameter (348, 349, 350, 351). Refer to the
Configuring Your 1394 Analog Servo System chapter
for more information.

rotation for Axis 0 (by default). This is a display LED
only.
When you first apply power to the drive, the HIM cycles through a
series of displays:
• System/drive name
• HIM ID number
• Communication status
