Digital input
function

Description

[11] Start reversing

Use for start/stop and for reversing at the
same time. Signals on

[8] start

are not

allowed at the same time. 0=stop, 1=start
reversing.

[14] Jog

Used for activating jog speed. See

parameter 3-11 Jog Speed [Hz]

. (Default

digital input 29).

[16] Preset ref bit 0

Enables a selection of 1 of the 8 preset
references according to

Table 4.5

[17] Preset ref bit 1

Enables a selection of 1 of the 8 preset
references according to

Table 4.5

[18] Preset ref bit 2

Enables a selection of 1 of the 8 preset
references according to

Table 4.5

[19] Freeze reference Freeze actual reference. The frozen

reference is now the point of enable/
condition for speed up and speed down
to be used. If speed up/speed down is
used, a speed change always follows ramp
2 (

parameter 3-51 Ramp 2 Ramp Up Time

and

parameter 3-52 Ramp 2 Ramp Down

Time

) in the range

parameter 3-02 Minimum Reference

parameter 3-03 Maximum Reference

[20] Freeze output

Freezes actual reference. The frozen
reference is now the point of enable/
condition for speed up and speed down
to be used. If speed up/speed down is
used, the speed change always follows
ramp 2.

[21] Speed up

For digital control of the up/down speed
(motor potentiometer). Activate this
function by selecting either freeze
reference or freeze output. When speed
up is activated for less than 400 ms, the
resulting reference is increased by 0.1%. If
speed up is activated for more than 400
ms, the resulting reference ramps
according to ramp 1 in

parameter 3-41 Ramp 1 Ramp Up Time

[22] Speed down

Same as

[21] Speed up

, but reference

decreases.

[23] Set-up select bit
0

Selects 1 of the 2 set-ups. Set

parameter 0-10 Active Set-up

to multi set-

up.

[32] Pulse Input

Select pulse input when using a pulse
sequence as either reference or feedback.
Scaling is done in parameter group

5-5*

Pulse Input

. Available only for terminal 29.

[34] Ramp bit 0

Select which ramp to use. Logic 0 selects
ramp 1, while logic 1 selects ramp 2.

[37] Fire mode

A signal applied puts the frequency
converter into fire mode and disregards all
other commands. See

24-0* Fire Mode

Digital input
function

Description

[52] Run permissive

The input terminal, for which the run
permissive is programmed, must be logic
1 before a start command can be
accepted. Run permissive has a logic

AND

function related to the terminal, which is
programmed for

[8] Start

[14] Jog

, or

[20]

Freeze Output

. To start running the motor,

both conditions must be fulfilled. If run
permissive is programmed on multiple
terminals, run permissive only has to be
logic 1 on 1 of the terminals for the
function to be carried out. Run permissive
does not affect the digital output signal
for run request (

[8] Start

[14] Jog

, or

[20]

Freeze Output

) programmed in parameter

group

5-3* Digital Outputs

, or parameter

group

5-4* Relays

NOTICE

If no run permissive signal is applied
but either run, jog, or freeze
commands is activated, the status
line in the display shows either

Run

Requested

Jog Requested

, or

Freeze

Requested

[53] Hand Start

A signal applied puts the frequency
converter into hand on mode as if [Hand
On] is pressed and a normal stop
command is overridden. If the signal is
disconnected, the motor stops. To make
any other start commands valid, assign
another digital input to

Auto Start

and

apply a signal. The [Hand On] and [Auto
On] keys have no impact. The [Off] key
overrides

Hand Start

and

Auto Start

. Press

either [Hand On] or [Auto On] to
reactivate

Hand Start

and

Auto Start

. If
