13-28
Possible Causes What to Check and Suggested Measures
(6) A run command with higher
priority than the one
attempted was active.
Referring to the run command block diagram given in the FRENIC-VG
User's Manual, Chapter 4, check the higher priority run command using
Menu #2 "DATA CHECK" and Menu #4 "I/O CHECK" with the keypad.
Î Correct the wrong setting of function codes (e.g., cancel the higher
priority run command).
Î Correct wrong setting of function code H30 (Communications link
function, Mode selection) or cancel the higher priority run command.
(7) The speed limiter settings
were made incorrectly.
Check the data of function codes F76 (Speed limiter mode), F77 and F78
(Speed limiter levels 1 and 2).
Î Correct the data of F76 through F78.
(8) The coast-to-stop command
was effective.
Check the data of function codes E01 through E09 and the input signal
status of X terminals, using Menu #4 "I/O CHECK" on the keypad.
Î Release the coast-to-stop command setting.
Check the input signal status of terminal [EN], using Menu #4 "I/O
CHECK" on the keypad.
Î Short-circuit the terminal [EN] with terminal [PS].
(9) No input on [EN1] or
[EN2].
Check the input status of the EN terminal, using Menu #4 "I/O CHECK" on
the keypad.
Î Short-circuit each of [EN1] and [EN2] with [PS]. (Refer to Chapter 3,
Section 3.3.3.8 "Detailed functions of control circuit terminals."
(10) Broken wires, incorrect
connection or poor contact
with the motor. Or the motor
defective.
Check the wiring and the motor. (Measure the output current).
Î Repair the wires to the motor, or replace them.
Î Repair the motor or replace it.
Measure the output current.
Î Reduce the load (In winter, the load tends to increase.)
Î Increase the inverter and motor capacities.
(11) Overload
Check whether any mechanical brake is activated.
Î Release the mechanical brake, if any.
(12) Torque generated by the
motor was insufficient.
Check that the motor switching signal (selecting motor 1, 2 or 3) is correct
using Menu #4 "I/O CHECK" on the keypad and that the data of function
codes matches each motor.
Î Correct the motor switching signal.
Î Modify the function code data to match the connected motor.
Under V/f control
(13) Torque generated by the
motor was insufficient.
Check whether the reference speed is below the slip-compensated speed of
the motor (Function codes P10 and P11 for M1, A12 and A13 for M2, and
A112 and A113 for M3).
Î Change the reference speed so that it becomes higher than the
slip-compensated speed of the motor.
Check whether increasing the toque boost (Function code P35, A55, A155)
starts rotating the motor.
Î Increase the data of P35, A55 or A155.
Check the data of function code F04, A05 or A105.
Î Change the V/f pattern setting to match each motor.
(14) Wrong connection or poor
contact of DC reactor
(DCR)
Check the wiring between the main circuit terminals P1 and P(+).
Inverters of 55 kW in LD mode and inverters of 75 kW or above come with
a DCR as standard. Without connection of a DCR, these inverters cannot
run.
Î Connect a jumper bar or DCR correctly. Repair or replace wires to the
DCR.
