H1 Multi-Function Digital Input Selections
Open: No drive output
Open: Accel/decel is not held
Closed: The drive pauses during acceleration or deceleration and maintains the output
frequency.
Closed: Closes when an oH2 alarm occurs
Open: Function assigned by H3-14 is disabled.
Closed: Function assigned by H3-14 is enabled.
Open: Speed feedback for V/f Control with PG is enabled.
Closed: Speed feedback disabled.
Open: PI control
Closed: Integral reset
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.
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.
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.
Closed: Runs forward at the Jog frequency d1-17.
Closed: Runs reverse at the Jog frequency d1-17.
Closed: Resets faults if the cause is cleared and the Run command is removed.
Closed: Decelerates at the Fast Stop time set to C1-09.
Open: Motor 1 (E1-oo, E2-oo)
Closed: Motor 2 (E3-oo, E4-oo)
Open: Decelerates to stop at the Fast Stop time set to C1-09.
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).
Open: PID control enabled
Closed: PID control disabled
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.
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.
Closed: Samples the analog frequency reference and operates the drive at that speed.
20: N.O., Always detected, ramp to stop
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)
Closed: Resets the PID control integral value.
Open: Performs integral operation.
Closed: Maintains the current PID control integral value.
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.
