DANGER
EQUIPMENT IS AT LINE VOLTAGE WHEN AC POWER IS CONNECTED TO THE POWER UNIT. 3
PHASE AC POWER LINE MUST BE DISCONNECTED FROM THE POWER UNIT BEFORE IT IS SAFE
TO TOUCH ANY INTERNAL PARTS OF THIS EQUIPMENT.
START UP CHECK LIST
A.
BEFORE AC POWER IS APPLIED:
1.
DRIVE IS SUPPLIED AS A VOLTAGE REGULATOR. IF USED AS A VOLTAGE REGULATOR, CHECK THAT
JUMPER AT L51 ON THE REGULATOR CARD IS CONNECTED TO PIN “A” (ARMATURE FDBK)AT l52 SEE
W/D SHEET 2 OR I/M.
2.
IF DRIVE IS TO BE A SPEED REGULATOR, CHECK THAT JUMPER AT L51 ON THE REGULATOR CARD
IS CONNECTED TO PIN “T” (TACH FDBK) AT L49. BE SURE TACHOMETER IS CONNECTED TO
TACHOMETER FEEDBACK KIT AND SCALED PROPERLY. SEE TABLES IN NOTES OR 10 FOR TACH SCAL-
ING. SEE I/M.
3.
CHECK THAT THE CURRENT FEEDBACK JUMPER AT H63 ON THE REGULATOR CARD IS SET TO THE
PROPER TAP. REFER TO TABLE ON SH. 9 OF W/D, AND I/M.
4.
CHECK POLARITY OF ARMATURE AND FIELD WIRING.
5.
RECOMMENDED INITIAL POT SETTINGS.
(1) CURRENT LIMIT POT FACTORY PRESET TO 150%.
DOT 7. DO NOT DISTURB.
(2) IR COMP. POT FULLY CCW DOT 1
(3) MAX. SPEED POT FULLY CCW DOT 1
(4) MIN. SPEED POT FULLY CCW DOT 1
(5) ACCEL. POT FULLY CCW DOT 1
(6) DECEL. POT FULLY CCW DOT 1
B.
AFTER AC POWER IS APPLIED (BEFORE STARTING DRIVE)
DANGER
DANGEROUS VOLTAGES ARE PRESENT IN DRIVE WHENEVER AC VOLTAGE IS PRESENT, WHETHER
OR NOT DRIVE IS STARTED. DO NOT TOUCH ANY POWER CIRCUITS OR WIRING WHEN LINE
VOLTAGE IS ON.
1.
CHECK THAT AC LINE VOLTAGE IS WITHIN 10% OF RATED INPUT VOLTAGE. SEE SHEET 8.
2.
CHECK THAT FIELD VOLTAGE IS PRESENT AT MOTOR TERMINALS (F1, F2).
3.
TURN THE SPEED OR VOLTAGE REFERENCE INITIALLY TO “0”.
DANGER
DURING THE INITIAL START-UP AND ADJUSTMENTS, BE PREPARED TO STOP DRIVE IN CASE
INCORRECT SET-UP IN FIELD OR TACHOMETER SHOULD CAUSE UNCONTROLLED ACCELERATION OF
THE MOTOR. IF THE DRIVE IS NOT SHUT DOWN IMMEDIATELY UNDER SUCH CIRCUMSTANCES,
PERSONAL INJURY AND/OR MACHINE DAMAGE MAY RESULT.
CAUTION: NEVER STOP DRIVE EXCEPT UNDER EMERGENCY BY INTERRUPTING INCOMING POWER.
DAMAGE TO THE DRIVE MAY RESULT.
DRIVE ADJUSTMENT PROCEDURE
CAUTION: DO NOT PLUG A KIT PCB INTO (OR REMOVE IT FROM) THE DRIVE WITHOUT FIRST
TURNING CIRCUIT BREAKER TO “OFF” POSITION. DO NOT USE AN OHMMETER TO CHECK
TRANSISTORS OR ASSOCIATED CIRCUITS. A TEST METER ADAPTOR KIT IS AVAILABLE TO
TEST REGULATOR CIRCUITS.
NOTE: ADJUSTMENTS BELOW REFER ONLY TO STANDARD DRIVES. FOR CUSTOM DRIVE SYSTEM SETTINGS
REFER TO SYSTEM’S DOCUMENTATION.
