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
b5-39: PID Setpoint User Display, PID Setpoint Display Digits
Setst a user-defined display for the PID setpoint (b5-19) and PID feedback monitors (U5-01, U5-04). The setting value is equal
to the number of decimal places.
No. Name Setting Range Default
b5-39 PID Setpoint Display Digits 0 to 3 1
Setting 0: No Decimal Places
Setting 1: One Decimal Place
Setting 2: Two Decimal Places
Setting 3: Three Decimal Places

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 4.20.
Table 4.20 Accel/Decel Time Selection by Digital Input
Accel/Decel Time Sel. 1
H1-oo = 7

0 0 C1-01 C1-02
1 0 C1-03 C1-04
Figure 4.41 shows an operation example for changing accel/decel. times. The example below requires that the stopping method
be set for “Ramp to stop” (b1-03 = 0).
