12.
The output of the module is controlled by the “Deadman” input at
terminals 10 & 11 of J1. Applying 24V DC or 115V AC to this input
will cause the module to operate. The front panel “Dedman” LED
will be off. When this input is de-energized, the module output will
be connected to logic ground, thus disabling output. At this point the
“Dedman” LED will illuminate.
Energize the “Deadman” input with 24V DC or 115V AC.
ATTENTION: During subsequent steps, the servomotor may
begin to rotate and cause incorrect machine movement when the
drive is enabled. Be prepared to remove drive power by opening
(MCB) or the branch circuit disconnect device if this occurs.
This movement may be due to a wiring error or system
component malfunction and must be corrected before
proceeding with this procedure. Damage to machine system
components can occur due to uncontrolled machine movements.

Apply power to the drive and module. Initiate a Start command by
selecting speed input, SEL1. Command a speed through the speed
pot, SPD 1 that represents approximately 10% of maximum speed
(i.e. 1V DC).
The motor should rotate slowly under control (following the speed
pot). If the motor is uncontrollable or rotates incorrectly, de-energize
SEL 1. Remove all power and check wiring.
If the application requires reverse direction, use the FWD/REV
toggle switch to check operation in the reverse direction.
14.
With a zero velocity command from the module, use the drive
parameter 210 (Analog to Digital Converter Offset) to set zero
motor speed. Refer to Chapter 6 for more information on this
parameter.
Important: The motor may begin to move slowly after a period of
time (several minutes) even though parameter 210 is set to zero.
15.
Rotate the speed pot (SPD 1) fully counterclockwise. Adjust the
Analog Velocity Gain parameter (211) if necessary to give the
desired motor speed.
16.
Check the accel/decel rate settings at speeds selected for the
application. Refer to steps 10 & 11.
17.
If applicable, repeat steps 6-16 for any of the other three preset
speeds
