7.6 Parameter Setting Errors
364 YASKAWA SIEPC71061705H GA700 Series Technical Manual
Code Name Causes Possible Solutions
oPE13 Pulse Monitor Selection Error
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].
Set H6-06 correctly.
Code Name Causes Possible Solutions
oPE15 Torque Control Setting Error
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]
Correct the parameter settings.
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]
Correct the parameter settings.
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.)]
Correct the parameter settings.
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]
Correct the parameter settings.
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]
Correct the parameter settings.
Code Name Causes Possible Solutions
oPE16 Energy Saving Constants Error
The Energy Saving parameters are not set in the
applicable setting range.
Make sure that E5-xx is set correctly as specified by the motor
nameplate data.
Code Name Causes Possible Solutions
oPE18 Online Tuning Param Setting Err
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.
Set E2-02, E2-03, and E2-06 correctly.
Code Name Causes Possible Solutions
oPE20 PG-F3 Setting Error
The value set in F1-01 [Encoder 1 Pulse Count
(PPR)] does not agree with the number of encoder
pulses.
• Examine the F1-01 value and the number of encoder pulses.
• Set F1-01 correctly.
The calculation encoder signal frequency at
maximum speed is more than 20 kHz.
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.
