DC-brake in-
verse
Inverted input for DC braking (NC). Stops the motor by energizing it with DC current for a certain time
period, see
parameter 2-01 DC Brake Current
. The function is only active when the value in
parameter
2-02 DC Braking Time
is different from 0. This selection is not possible when
parameter 1-10 Motor Con-
struction
is set to
[1] PM non-salient SPM
.
[6]
Stop inverse
The stop inverse function generates the stop function when the selected terminal goes from logical
level 1 to 0 (not latched). Stop is performed according to selected ramp time.
[7]
External Inter-
lock
Same function as coast stop, inverse, but external interlock generates the alarm message
external fault
on the display when the terminal programmed for coast inverse is logic 0. If programmed for external
interlock, the alarm message is also active via digital outputs and relay outputs. If the cause for the
external interlock is removed, the alarm can be reset using a digital input, fieldbus, or the [Reset] key.
[8]
Start
Select start for a start/stop command. Logic 1 = start, logic 0 = stop. (Default digital input 18).
[9]
Latched start
If a pulse is applied for a minimum of 2 ms, the motor starts. The motor stops when stop inverse is
activated.
[10]
Reversing
Change direction of motor shaft rotation. The reversing signal only changes the direction of rotation, it
does not activate the start function. Select
[2] Both directions
in
parameter 4-10 Motor Speed Direction
. 0
= normal, 1 = reversing.
[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
Enable a selection of 1 of the 8 preset references according to
[17]
Preset ref bit 1
Enable a selection of 1 of the 8 preset references according to
[18]
Preset ref bit 2
Enable a selection of 1 of the 8 preset references according to
[19]
Freeze refer-
ence
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 (
pa-
rameter 3-51 Ramp 2 Ramp Up Time
and
parameter 3-52 Ramp 2 Ramp Down Time
) in the range
parame-
ter 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 setups. Set
parameter 0-10 Active Set-up
to multi setup.
[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 into fire mode and disregards all other commands. See
parameter group 24-0*
Fire Mode
.
[52]
Run permissive
The input terminal, for which the run permissive is programmed, must be logic 1 before a start com-
mand can be accepted. Run permissive has a logic AND function related to the terminal, which is pro-
grammed 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
.
