CAUTION: Megger Test:
Do not conduct megger tests between the Drive main circuit terminals, or control circuit terminals.
Refer to Section 7 "Maintenance and Inspection."
Test Run Check Points
Use a low frequency reference setting of about 5 Hz to test Drive operation.
The following operating conditions must be confirmed:
1. Smooth motor rotation.
2. Correct direction of equipment rotation.
3. No abnormal vibrations and noise from the motor over full speed range.
4. Smooth acceleration and deceleration over full speed range.
Selecting Operation Method
The following methods can be selected to input the RUN/STOP signals and for frequency setting.
NOTES:
*1: F_02 cannot be changed when there is a short circuit (jumper)between either FWD-CM or REV-CM.
*2: Multistep speed operation (up to 8 steps are possible)
The frequencies of step 1 to step 7 are set with the Function Codes F_21 to F_27 and selected
with the terminals X1, X2 and X3 (Additional 8 steps available with F_43 = 1 and F_44 to F_51
using X4).
If input signals are provided to terminals X1, X2 and X3, then data setting of F_01 (settings made by
keypad panel or analog signal are ignored) and multistep speed operation is controlled by these
terminal signals.
*3: F_02 =1 Stop key on the keypad active
F_02 = 2 Stop key on the keypad inactive
Operation
Pre-Operation Inspection
After completion of installation and wiring work, inspect the following items before the power supply to the Drive is
switched on.
CAUTION:
1. Check for wiring errors. (Especially the main circuit wiring: connection of the three
(single) phase AC power supply to the terminals L1, L2, L3 (L1, L2)).
2. Check that all loose wire strands, metal chips and unnecessary screws, etc. have been removed.
3. Check that all screws, terminals, and components are tight.
4. Check that the wire ends of crimp terminals are not in contact with other terminals.
