YASKAWA U1000 iQpump Drive, Technical Manual

Page: 396 / 706

Digital Operator Display Error Name
Cause Possible Solutions
The following simultaneous contradictory settings have occurred: C6-05 >
6 and C6-04 > C6-03 (carrier frequency lower limit is greater than the upper
limit).
If C6-05 ≤ 6, the drive operates at C6-03.
Correct the parameter settings.
The upper and lower limits between C6-02 and C6-05 are contradictory.
Digital Operator Display Error Name
oPE13
Pulse Monitor Selection Error
Incorrect setting of monitor selection for pulse train (H6-06).
Cause Possible Solutions
Scaling for the pulse train monitor is set to 0 (H6-07 = 0) while H6-06 is not
set to 101, 102, 105, or 116.
Change scaling for the pulse train monitor or set H6-06 to 101, 102, 105,
or 116.
Digital Operator Display Error Name
oPE15
Torque Control Setting Error
Parameter settings that are not allowed in combination with Torque Control
have been set.
Cause Possible Solutions
Torque Control is enabled (d5-01 = 1) while the Speed/Torque Control
switch function is assigned to a digital input (H1- oo = 71).
Correct the parameter settings.
Either d5-01 is set to 1 to enable Torque Control, or the Speed/Torque Control
switch is assigned to a digital input H1- oo = 71, while at the same time:
• Feed Forward is enabled (n5-01 = 1) or
• Droop Control is enabled (b7-01 ≠ 0)
Digital Operator Display Error Name
oPE16 Energy Savings Constants Error
Cause Possible Solutions
In AOLV/PM, the automatically calculated energy saving coefficients are
out of the allowable range.
Check and correct the motor data in E5 parameters.
Digital Operator Display Error Name
oPE18
Online Tuning Parameter Setting Error
Parameters controlling online tuning are not set correctly.
Cause Possible Solutions
One of the following errors occurred while online tuning was enabled in OLV
(A1-02 = 2):
• E2-02 was set below 30% of the original default value
• E2-06 was set below 50% of the original default value
• E2-03 = 0
Set E2-02, E2-03, and E2-06 to the correct values.
Digital Operator Display Error Name
oPE20
PG-F3 Setting Error
The encoder signal frequency is too high.
Cause Possible Solutions
With the entered encoder resolution (F1-01), maximum output frequency
(E1-04), and motor pole number (E5-04), the calculation encoder signal
frequency exceeded 50 kHz (with PG-F3 option).
• Set F1-01 to the correct encoder resolution.
• Reduce the maximum output frequency of the drive in parameter E1-04
so the encoder signal frequency at maximum speed is lower than 50 kHz.
Digital Operator Display Error Name
oPE30
Incorrect Input Voltage Adjustment
The input voltage offset adjustment has not been performed.
Cause Possible Solutions
• o2-04, Drive Model Selection, setting changed.
• EEPROM failed for the input voltage offset.
Contact Yaskawa or your nearest sales representative for information on
clearing the error.
