3-26 Receiving and Installation
MN715J
Pre-Operation Checklist
Check of electrical items.
1.
Verify AC line voltage at source matches control rating.
2.
Inspect all power connections for accuracy, workmanship and tightness
as well as compliance to codes.
3.
Verify control and motor are grounded to each other and the control is
connected to earth ground.
4.
Check all signal wiring for accuracy.
5.
Be certain all brake coils, contactors and relay coils have noise
suppression. This should be an R-C filter for AC coils and reverse
biased diodes for DC coils. MOV type transient suppression is not
adequate for noise suppression.
Check of Motor and Couplings
1.
Verify freedom of motion of motor shaft.
2.
Verify that all motor couplings are tight without backlash.
3.
If holding brakes are used, verify they are properly adjusted to fully
release and set to the desired torque value.
Power-up Procedure
1.
Turn power on. Be sure no faults are displayed on the keypad display.
2.
Set the Level 1 Input block, Operating Mode to “Keypad”.
3.
Set the Level 2 Output Limits block, “MIN Output FREQ” parameter.
4.
Set the Level 2 Output Limits block, “MAX Output FREQ” parameter.
5.
If the desired peak current limit setting is not correct, set the Level 2
Output Limits block, “PK Current Limit” parameter as desired.
6.
Enter the following motor data in the Level 2 Motor Data block
parameters:
Motor Rated Amps (FLA)
Motor Rated Speed (base speed)
Motor Rated Frequency (Nameplate)
7.
If External Dynamic Brake hardware is used, set the Level 2 Brake
Adjust block parameters as desired.
8.
Set the Level 1 V/HZ Boost block, “V/HZ Profile” parameter for the
correct V/Hz ratio for your application.
9.
If the load is a high initial starting torque type, the torque boost and Accel
time may need to be increased. Set the Level 1 V/HZ Boost block,
“Torque Boost” and the Level 1 Accel/Decel Rate block, “ACCEL TIME
#1” as required.
10. Select and program additional parameters to suit your application.
The control is now ready for use in keypad mode. The terminal strip wiring
may be changed and different parameter values used for another operating
mode.
