Start-Up

Chapter Objectives Chapter 7 provides the steps needed to properly start-up the 1391B-ES AC

Servo Controller. Included in the procedure are typical adjustments and

voltage checks to assure proper operation.

Start-Up Procedure The following procedure provides the required steps to start-up the

1391B-ES AC Servo Controller in velocity and position mode.

ATTENTION: Power must be applied to the controller to

perform many of the adjustments specified in the following

paragraphs. Voltages behind the front panel are at incoming line

potential. To avoid injury to personnel and/or damage to

equipment, only qualified service personnel should perform the

following start-up procedures. Thoroughly read and understand

the following procedure before beginning the Start-Up

Procedure. If an event does not occur while performing this

start-up, Do Not Proceed. Remove Power by opening the branch

circuit disconnect device and correct the malfunction before

continuing.

ATTENTION: This product contains stored energy devices. To

avoid hazard of electrical shock, verify that all voltage on the

capacitors has been discharged before attempting to service,

repair or remove this unit.

Voltage at terminals 9 (+) and 7 (–) of TB5 must be “0.00” as

measured with a standard digital voltmeter or multimeter.

Only qualified personnel familiar with solid-state control

equipment and safety procedures in publication NFPA 70E

should attempt this procedure.

o 1. Assure that all power to the controller is off. Most start-up

difficulties are the result of wiring errors. Therefore, prior to

applying power to the primary of the transformer or system, check

all of the system interconnection wiring.

o 2. Check terminal block connections as described in Chapter 5 and

Appendix B.
