C-4 Using the Human Interface Module (HIM)
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. 
Change Direction 
(Jog/Digital Velocity Reference Modes 
Only)
Pressing this key causes the motor to change direction. The 
appropriate direction indicator illuminates to indicate 
direction.
Direction LEDs (Indicators)
These LEDs illuminate to indicate the direction of motor 
rotation for Axis 0 (by default). This is a display LED 
only.
Understanding HIM Operation
When you first apply power to the drive, the HIM cycles through a 
series of displays:
• System/drive name
• HIM ID number
• Communication status
• Status display
