Baseblock command (N.C.)
Open: No drive output
A
Accel/decel ramp hold
Open: Accel/decel is not held
Closed: The drive pauses during acceleration or deceleration and maintains the output
frequency.
B
Drive overheat alarm (oH2)
Closed: Closes when an oH2 alarm occurs
C
Analog terminal input selection
Open: Function assigned by H3-14 is disabled.
Closed: Function assigned by H3-14 is enabled.
F
Through mode
Select this setting when using the terminal in a pass-through mode. The terminal does not
trigger a drive function but can be used as digital input for the controller the drive is connected
to.
10
Up command
The drive accelerates when the Up command terminal closes, and decelerates when the Down
command closes. When both terminals are closed or both are open, the drive holds the
frequency reference. The Up and Down commands must always be used in conjunction with
one another.
11
Down command
The drive accelerates when the Up command terminal closes, and decelerates when the Down
command closes. When both terminals are closed or both are open, the drive holds the
frequency reference. The Up and Down commands must always be used in conjunction with
one another.
12
Forward Jog
Closed: Runs forward at the Jog frequency d1-17.
13
Reverse Jog
Closed: Runs reverse at the Jog frequency d1-17.
14
Fault reset
Closed: Resets faults if the cause is cleared and the Run command is removed.
15
Fast Stop (N.O.)
Closed: Decelerates at the Fast Stop time set to C1-09.
17
Fast Stop (N.C.)
Open: Decelerates to stop at the Fast Stop time set to C1-09.
18
Timer function input
Triggers the timer set up by parameters b4-01 and b4-02. Must be set in conjunction with the
timer function output (H2-oo = 12).
19
PID disable
Open: PID control enabled
Closed: PID control disabled
1A
Accel/decel time selection 2
Used in conjunction with an input terminal set for “Accel/decel time selection 1”
(H1-oo = 7), and allows the drive to switch between accel/decel times 3 and 4.
1B
Program lockout
Open: Parameters cannot be edited (except for U1-01 if the reference source is assigned to
the digital operator).
Closed: Parameters can be edited and saved.
1E
Reference sample hold
Closed: Samples the analog frequency reference and operates the drive at that speed.
20 to 2F External fault

21: N.C., Always detected, ramp to stop
22: N.O., During run, ramp to stop
23: N.C., During run, ramp to stop
24: N.O., Always detected, coast to stop
25: N.C., Always detected, coast to stop
26: N.O., During run, coast to stop
27: N.C., During run, coast to stop
28: N.O., Always detected, Fast Stop
29: N.C., Always detected, Fast Stop
2A: N.O., During run, Fast Stop
2B: N.C., During run, Fast Stop
2C: N.O., Always detected, alarm only (continue running)
2D: N.C., Always detected, alarm only (continue running)
2E: N.O., During run, alarm only (continue running)
2F: N.C., During run, alarm only (continue running)
30
PID integral reset
Closed: Resets the PID control integral value.
31
PID integral hold
Open: Performs integral operation.
Closed: Maintains the current PID control integral value.
32
Multi-Step Speed
Reference 4
Used in combination with input terminals set to Multi-Step Speed Reference 1, 2, and 3. Use
parameters d1-09 to d1-16 to set reference values.
34
PID soft starter cancel
Open: PID soft starter is enabled.
Closed: Disables the PID soft starter b5-17.
35
PID input level selection
Closed: Inverts the PID input signal.
40
Forward run command
(2-Wire sequence)
Open: Stop
Closed: Forward run
Note:
Cannot be set together with settings 42 or 43.
