n b5-03: Integral Time Setting (I)
Sets the time constant used to calculate the integral of the PID input. The shorter the integral time set to b5-03, the faster the
offset will be eliminated. If the integral time is set too short, however, overshoot or oscillation may occur. To turn off the
integral time, set b5-03 to 0.00.
No. Name Setting Range Default
b5-03 Integral Time Setting (I) 0.0 to 360.0 s 1.0 s
n b5-09: PID Output Level Selection
Reverses the sign of the PID controller output signal. Normally a positive PID input (feedback smaller than setpoint) leads to
positive PID output.
No. Parameter Name Setting Range Default
b5-09 PID Output Level Selection 0, 1 0
Setting 0: Normal Output
A positive PID input causes an increase in the PID output (direct acting).
Setting 1: Reverse Output
A positive PID input causes a decrease in the PID output (reverse acting).
n b5-38, b5-39: PID Setpoint User Display, PID Setpoint Display Digits
When parameter b5-20 is set to 3, parameters b5-38 and b5-39 set a user-defined display for the PID setpoint (b5-19) and PID
feedback monitors (U5-01, U5-04).
Parameter b5-38 determines the display value when the maximum frequency is output and parameter b5-39 determines the
number of digits. The setting value is equal to the number of decimal places.
No. Name Setting Range Default
b5-38 PID Setpoint User Display 1 to 60000
Determined by
b5-20
b5-39 PID Setpoint Display Digits 0 to 3
Determined by
b5-20
Setting 0: No Decimal Places
Setting 1: One Decimal Place
Setting 2: Two Decimal Places
Setting 3: Three Decimal Places
n C1-01 to C1-04: Accel, Decel Times 1 and 2
Two different sets of acceleration and deceleration times can be set in the drive by digital inputs, motor selection, or switched
automatically.
Acceleration time parameters always set the time to accelerate from 0 Hz to the maximum output frequency (E1-04).
Deceleration time parameters always set the time to decelerate from maximum output frequency to 0 Hz. C1-01 and C1-02
are the default active accel/decel settings.
No. Parameter Name Setting Range Default
C1-01 Acceleration Time 1
0.0 to 6000.0 s <1> 10.0 s
C1-02 Deceleration Time 1
C1-03 Acceleration Time 2
C1-04 Deceleration Time 2
<1> The setting range for the acceleration and deceleration times is determined by the accel/decel time setting units in C1-10. For example, if the time
is set in units of 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
Switching Acceleration Times by Digital Input
Accel/decel time 1 is active by default if no input is set. Activate accel/decel times 2, 3, and 4 by digital inputs
(H1-oo = 7 and 1A) as explained in Table 4.19 .
