Function Description Page
9 Baseblock command (N.C.) Open: No drive output 207
A Accel/decel ramp hold
Open: Accel/decel is not held
Closed: The drive pauses during acceleration or deceleration and maintains the output
frequency.
207
B Drive overheat alarm (oH2)
Closed: An external device has triggered an oH2 alarm. Sets Drive Overheat Pre-alarm Multi-
Function Digital Output 20h.
208
C Analog terminal input selection
Open: Function assigned by H3-14 is disabled.
Closed: Function assigned by H3-14 is enabled.
208
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.
208
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.
208
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.
208
12 Forward Jog Closed: Runs forward at the Jog frequency d1-17. 209
13 Reverse Jog Closed: Runs reverse at the Jog frequency d1-17. 209
14 Fault reset Closed: Resets faults if the cause is cleared and the Run command is removed. 209
15 Fast Stop (N.O.) Closed: Decelerates at the Fast Stop time set to C1-09. 209
17 Fast Stop (N.C.) Open: Decelerates to stop at the Fast Stop time set to C1-09. 209
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).
210
19 PID disable
Open: PID control enabled
Closed: PID control disabled

1A
<1>
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.
210
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.
210
1E Reference sample hold Closed: Samples the analog frequency reference and operates the drive at that speed. 210

2E: N.O., During run, alarm only (continue running)
2F: N.C., During run, alarm only (continue running)
211
30 PID integral reset Closed: Resets the PID control integral value. 211
31 PID integral hold
Open: Performs integral operation.
Closed: Maintains the current PID control integral value.
211
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.
211
34 PID soft starter cancel
Open: PID soft starter is enabled.
Closed: Disables the PID soft starter b5-17.
211
