1. Machine does not seem to have enough power to start
2. Converter does not start. It makes a growling sound
3. Converter does not start. Absolutely nothing happens.
4. Converter does not have a smooth quiet sound
5. My machine runs backwards
6. I blew a start capacitor on start-up
7. The idler has a squealing noise
8. The idler is very hot
9. My machine has contactors that are clicking or lights that are flickering
10. My CNC machine kicks out when I start the spindle
11. My voltage is too high
12. My voltage is too low
13. My voltage balance is not as good as I want
14. I measure 120 volts from T1 and T2 to ground, but not from T3 to ground
15. My Idler generator motor makes a ringing noise
16. My breaker is popping
Answer A:
Check to make sure your converter is big enough. If not, a second converter
of equal size can be installed in parallel to your converter to double its size.
Ask us about our Autolink.
Answer B:
Make sure your wire is big enough. Use the minimum wire size suggested on
pages 9 or 10. Go up at least one size for every 50 feet of run. Wire may
need to be upsized for hard loads.
Answer C:
Check the connections. L1 and L2 are the single phase input and should
measure about the same voltage from line to line as the incoming.
Answer D:
Check to make sure the idler is hooked up for its rated voltage. If it is 208-
240 volts, make sure lines 4, 5 & 6 are electrically tied together, insulated,
and not grounded. If it is for higher voltages (480 volts), make sure lines
(4,7), (5,8), and (6,9) are electrically tied together, insulated, and not
grounded.
Answer E:
By switching any two of the three output lines to the idler, the direction can be
reversed. Trying different combinations of A, B and C will result in a slightly
varying voltage balance.
Answer F:
Although small, the vibrations caused by the idler can resonate depending on
how it is mounted. Never bolt the motor to a rigid structure. Visit

Answer G:
The GENTEC/BALDOR idlers are rated up to 150° C. It may be normal for
them to run hot. High current on one or more lines may also cause them to
run hot. A good voltage balance means a good current balance.
Answer H:
All controls should be run from T1 and T2 (the single phase lines). These
lines do not fluctuate voltage as much as T1 to T3 or T2 to T3. If your
machine does not have these clearly marked, try different combinations of
T1, T2 and T3.
Answer I:
You are probably getting a low voltage error. Slow the acceleration down on
the spindle in order to reduce the inrush current.
