Section 3
Start-up
Startup 3-1
MN1269
Overview
The start-up information provided in this section contains the procedures necessary to get
each axis running and properly tuned using the 6 adjustment potentiometers on the servo
control. Each axis should be started up independently to insure that catastrophic
problems do not cause damage to the equipment. It is further recommended that the
load is not connected to the servo control until you are familiar with the control.

Start-up (Power On)
To minimize the potential damage to the machine during power up, disconnect all axis
except the first (X-axis).
1.
Apply the 115 VAC to the AC power input.
2.
Observe that the fan starts and 4 of the green LED’s on the logic power supply
(+15V, –15V, AC, and ”BUS”) illuminate.
3.
Observe that the servomotor on number 1 axis (X) did not rotate. If the
servomotor runs up to a high speed at an uncontrolled rate, reverse the
tachometer or motor power leads.
