Possible Causes What to Check and Suggested Measures
(4) The external circuit wiring
to terminals [X1] to [X9] or
signal assignment to those
terminals is wrong.
Check whether the reference speed has been entered correctly, using Menu
#4 "I/O CHECK" on the keypad.
Î Connect the external circuit wires to terminals [X1] through [X9].
Î Correct the data of E01 to E14.
Î Correct the data of C05 to C21 (Multistep speed settings).
(5) A reference speed (e.g.,
multistep speed or via
communications link) with
higher priority than the one
attempted was active and
the reference speed was too
low.
Referring to the speed command block diagram given in the FRENIC-VG
User's Manual, Chapter 4, check the data of the relevant function codes and
what speed commands are being received, using Menu #2 "DATA CHECK"
and Menu #4 "I/O CHECK" with the keypad.
Î Correct any incorrect data of function codes (e.g. cancel the higher
priority reference speed).
(6) The acceleration or
deceleration time was too
long or too short.
Check the settings of the acceleration time and deceleration time (function
codes F07, F08, C35, C36, C46, C47, C56, C57, C66 and C67).
Î Change the acceleration/deceleration time to match the load.
(7) Overload. Measure the output current.
Î Reduce the load.
Check whether any mechanical brake is activated.
Î Release the mechanical brake.
Under V/f control
(8) Function code settings do
not agree with the motor
characteristics.
If auto-torque boost (Function code P35, A55, A155) is enabled, check
whether the data of P03, P04, P06, P07 and P08 for M1, A02, A03, A08,
A09 and A10 for M2, A102, A103, A108, A109 and A110 for M3 matches
the parameters of the motor.
Î Perform auto-tuning of the inverter for the motor to be used.
Under V/f control
(9) The output frequency does
not increase due to the
current limiter operation.
Decrease the value of the torque boost (Function code P35, A55, A155),
then run the motor again and check if the speed increases.
Î Adjust the value of the torque boost (P35, A55, A155).
Check the data of function codes F04, A05 and A105 to ensure that the V/f
pattern setting is right.
Î Match the V/f pattern setting with the motor ratings.
(10) The motor speed does not
increase due to the torque
limiter operation.
Check whether the data of torque limiter related function codes F40 through
F45 is correctly configured and the TL2/TL1 terminal command ("Select
torque limiter level") is correct.
Î Correct the data of F44 or F45 or enter the F40-CCL terminal command
("Cancel F40 (Torque limiter mode 1)").
(11) Incorrect settings of bias
and gain for analog input.
Check the data of function codes F17, F18 and E53 to E60.
Î Correct the bias and gain settings.
(12) The reference speed did not
change. (Keypad operation)
Check whether modifying the reference speed setting from the keypad
changes the reference speed.
Î Modify the reference speed setting by pressing the [] and [] keys.
Under vector control with speed
sensor
(13) Wrong wiring of the PG.
Check the wiring between the PG and the inverter for the phase sequence,
wire breaks, shielding and twisting.
Î Correct the wiring.
Under vector control with speed
sensor
(14) Wrong wiring between the
inverter and the motor.
Check the phase sequence (U, V, and W) of the main circuit wires between
the inverter and the motor.
Î Connect the inverter output terminals U, V, and W to the motor input
terminals U, V, and W, respectively.
