YASKAWA TOEPC7106171FD FP605 DRIVE INSTALLATION & PRIMARY OPERATION
Causes
A magnetic contactor was switched at the output.
The V/f pattern settings are incorrect.
The torque compensation gain is too large.
Electrical interference caused a problem.
The gain during overexcitation operation is too large.
The drive received a Run command while the motor
was coasting.
The motor code setting is incorrect for PM Control
Methods.
The current flowing in the motor is more than the
value set in L8-27 [Overcurrent Detection Gain] for
PM Control Methods.
The control method is set incorrectly for the motor.
The motor main circuit cable is too long.
Speed search does not complete at start when A1-02
= 8 [EZ Vector Control] and you use an induction
motor.
The relay or contactor on the soft-charge bypass relay
is damaged.
An overcurrent condition occurred during
overexcitation deceleration.
You are using a premium efficiency motor.
The output circuit between the drive and the motor is
open, and the drive output current is less than 5% of
E2-01 [Motor Rated Current (FLA)].
The option connected to connector CN5-A is not
compatible.
• The DIP switches on the JOHB-SMP3 Multi-
Protocol Ethernet Card are at factory default
settings.
• The DIP switches on the JOHB-SMP3 are not set
to a valid protocol.
• The DIP switches on the JOHB-SMP3 are set to a
valid protocol that is not supported by the drive.
The option failed. Check the LED flash pattern on the
option as specified by the option manual.
The option card connected to connector CN5-A is not
compatible.
The same option cards or the same type of option
cards are connected to connectors CN5-A and B.
20 Troubleshooting
Possible Solutions
Set the operation sequence to not turn ON or OFF the magnetic
contactor while the drive is outputting voltage.
• Examine the ratios between the V/f pattern frequency and
voltage. Decrease the voltage if it is too high compared to the
frequency.
• Adjust E1-04 to E1-10 [V/f Pattern Parameters]. For motor 2,
adjust E3-04 to E3-10.
Decrease the value set in C4-01 [Torque Compensation Gain] to
make sure that the motor does not stall.
Examine the control circuit lines, main circuit lines, and ground
wiring, and decrease the effects of electrical interference.
• Find the time when the fault occurs.
• If the fault occurs at the same time as overexcitation operation,
decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain] and consider the motor flux saturation.
• Examine the sequence and input the Run command after the
motor fully stops.
• Set b3-01 = 1 [Speed Search at Start Selection = Enabled] or set
H1-xx = 61, 62 [Speed Search from Fmax or Fref] to input speed
search commands from the MFDI terminals.
• Enter the correct motor code to E5-01 [PM Motor Code
Selection] as specified by the PM motor.
• For specialized motors, refer to the motor test report and set E5-
xx [PM Motor Settings] correctly.
Correct the value set in L8-27.
Set A1-02 [Control Method Selection] correctly.
Replace the drive with a larger capacity model.
When E9-01 = 0 [Motor Type Selection = Induction (IM)], set b3-
24 = 2 [Speed Search Method Selection = Current Detection Speed
Search].
• Re-energize the drive.
• If the fault stays, replace the control board or the drive.
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
Set these parameters:
• b3-03 [Speed Search Deceleration Time] = default value × 2
• L2-03 [Minimum Baseblock Time] = default value × 2
• L2-04 [Powerloss V/f Recovery Ramp Time] = default value × 2
Close the disconnected output circuit between the drive and the
motor.
Connect the option to the correct connector.
Remove power from the drive, wait for the charge light to go out,
then set the DIP switches on the JOHB-SMP3 to the desired
protocol.
Note:
If you connect a JOHB-SMP3 to drives with software versions
PRG: 01011 and earlier, the drives detect oFA00 [Option Not
Compatible with Port].
The "PRG" column on the nameplate on the right side of the
drive identifies the software version. You can also use U1-25
[SoftwareNumber FLASH] to identify the software version.
Replace the option.
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
Connect the option card to the correct connector.
