6.6 Operator Programming Errors
Digital Operator Display
• D control is being used on the setpoint
deviation and the frequency reference plus
the PID output (b5-01 = 4), D control is
being used on the feedback value and the
frequency reference plus the PID output
(b5-01 = 4).
• The frequency reference lower limit is set
to a value greater than 0 (d2-02 > 0).
The absolute value of the lower limit for PID
output is greater than the PID upper limit
(b5-34 > b5-06).
Digital Operator Display
Cause
V/f pattern setting error.
Digital Operator Display
Cause
The following simultaneous contradictory
settings: C6-05 is greater than 6 and C6-04 is
greater than C6-03 (carrier frequency lower
limit is greater than the upper limit). If C6-05
is less than or equal to 6, the drive operates at
C6-03.
Upper and lower limits between C6-02 and
C6-05 contradict each other.
Digital Operator Display
Cause
Scaling for the Pulse Train monitor is set to 0
(H6-07 = 0) while H6-06 is not set to 000, 031,
101, 102, 105, or 116.

Set parameters b5-01 and d2-02 to the proper values.
Set parameters b5-34 and b5-06 to the proper values.
V/f Data Setting Error
One or more of the parameters listed below are not set according to the formula:
oPE10
• E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
• E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04
Correct the settings for E1-04, E1-06, E1-07, E1-09, and E1-11.
For motor 2, correct E3-04, E3-06, E3-07, E3-09, and E3-11.
Carrier Frequency Setting Error
oPE11
Correct the setting for the carrier frequency.
Correct the parameter settings.
Pulse Monitor Selection Error
oPE13
Incorrect setting of monitor selection for Pulse Train (H6-06).
Change scaling for the Pulse Train monitor or set H6-06 to 000, 031, 101, 102, 105, or 116.
