YASKAWA SIEPC71061737D GA800 Drive Technical Reference
Causes
These parameters are set at the same time:
• C6-05 > 6 [Carrier Freq Proportional Gain > 6]
• C6-04 > C6-03 [Carrier Frequency Lower Limit
> Carrier Frequency Upper Limit]
Note:
When C6-05 < 7, C6-04 becomes disabled. The
drive sets the carrier frequency to the value set to
C6-03.
C6-02 to C6-05 settings are not in the applicable
setting range.
Causes
H6-06 = 101, 102, 105, or 116 [Terminal MP
Monitor Selection = Frequency Reference, Output
Frequency, Motor Speed, Output Frequency after Soft
Starter] has not been set when H6-07 = 0 [Terminal
MP Frequency Scaling = 0 Hz].
Causes
More than one parameter is selecting torque control at
the same time.
• d5-01 = 1 [Torque Control Selection = Torque
Control]
• H1-xx = 71 [MFDI Function Select = Torque
Control]
Droop control and Feed Forward control are enabled
at the same time that torque control is selected.
• d5-01 = 1 or H1-xx = 71
• b7-01 ≠ 0.0 [Droop Control Gain ≠ 0.0%] or n5-
01 = 1 [Feed Forward Control Selection =
Enabled]
KEB Ride-Thru 2 (N.O., N.C.) is enabled at the same
time that torque control is selected.
• d5-01 = 1 or H1-xx = 71
• H1-xx = 7A [KEB Ride-Thru 2 Activate (N.C.)] or
H1-xx = 7b [KEB Ride-Thru 2 Activate (N.O.)]
After a momentary power loss, drive operation will
enable KEB when torque control is selected.
• d5-01 = 1 or H1-xx = 71
• L2-01 = 3, 4, 5 [Power Loss Ride Through Select
= Kinetic Energy Backup: L2-02, Kinetic Energy
Backup: CPU Power, or Kinetic Energy Backup:
DecelStop]
Optimal deceleration or overexcitation deceleration 2
is enabled at the same time that torque control is
selected.
• d5-01 = 1 or H1-xx = 71
• L3-04 = 2, 5 [Stall Prevention during Decel =
Intelligent (Ignore Decel Ramp), Overexcitation/
High Flux 2]
Causes
The Energy Saving parameters are not set in the
applicable setting range.
Causes
The parameters that control online tuning are set
incorrectly. In OLV control, one of these parameters
was set when n6-01 = 2 [Online Tuning Selection =
Voltage Correction Tuning]:
• E2-02 [Motor Rated Slip] is set to 30% of the
default setting or lower.
• E2-06 [Motor Leakage Inductance] is set to 50%
of the default setting or lower.
• E2-03 = 0 [Motor No-Load Current = 0 A] has
been set.
Causes
The value set in F1-01 [Encoder 1 Pulse Count
(PPR)] does not agree with the number of encoder
pulses.
The calculation encoder signal frequency at
maximum speed is more than 20 kHz.
7.6 Parameter Setting Errors
Possible Solutions
Set C6-02 to C6-05 correctly.
Possible Solutions
Set H6-06 correctly.
Possible Solutions
Correct the parameter settings.
Correct the parameter settings.
Correct the parameter settings.
Correct the parameter settings.
Correct the parameter settings.
Possible Solutions
Make sure that E5-xx is set correctly as specified by the motor
nameplate data.
Possible Solutions
Set E2-02, E2-03, and E2-06 correctly.
Possible Solutions
• Examine the F1-01 value and the number of encoder pulses.
• Set F1-01 correctly.
Decrease the value set for E1-04 [Maximum Output Frequency] and
make sure that the output frequency of the encoder is not more than
20 kHz.
