2 : 2 decimal places
3 : 3 Decimal Places
■ b5-40: Fref Mon@PID
No.
(Hex.)
Name Description
Default
(Range)
b5-40
(017F)
Fref Mon@PID
Sets the contents for monitor U1-01 [Frequency Reference] in PID control.
0
(0, 1)
0 : U1-01 with PID Output
Monitor U1-01 shows the frequency reference that was increased or decreased by the PID output.
1 : U1-01 without PID Output
Monitor U1-01 shows the actual frequency reference.
■ b5-47: PID Out Rev Operation Mode
No.
(Hex.)
Name Description
Default
(Range)
b5-47
(017D)
PID Out Rev Operation
Mode
Sets reverse motor rotation when the PID control output is negative.
1
(0, 1)
This parameter is enabled when b5-01 = 1 [PID Enable = Enabled].
0 : Lower Limit is Zero
When PID output is negative, PID output is limited to 0 and drive output is shut off.
1 : Negative Output Accepted
When the PID output is negative, the motor will rotate in reverse.
■ b5-53: PID I Ramp Limit
No.
(Hex.)
Name Description
Default
(Range)
b5-53
(0B8F)
RUN
PID I Ramp Limit
Sets the responsiveness of PID control when the PID feedback changes quickly.
0.0 Hz
(0.0 - 10.0 Hz)
Note:
• This parameter is disabled when set to 0.0 Hz.
• When b5-53 > 0.0 Hz and the drive enables the integrator ramp limit, the PID integrator value limit is the range set by the output
frequency ± b5-53.
• When the PID feedback changes quickly, gradually decrease the this parameter in 0.1 Hz increments to decrease the speed of the
response of PID control.
■ b5-54: PID Softstarter Selection
No.
(Hex.)
Name Description
Default
(Range)
b5-54
(0BB7)
PID Softstarter Selection
Sets how the soft-starter responds to PID input/output.
0
(0, 1)
Table 12.16 shows how the soft-starter responds to PID input/output.
