Option Function
[9] Latched start If a pulse is applied for minimum 2 ms, the motor starts. The motor stops when stop inverse is activated,
or a reset command (via DI) is given.
[10] Reversing (Default digital input 19). Change the direction of motor shaft rotation. Select logic 1 to reverse. The re-
versing signal only changes the direction of rotation. It does not activate the start function. Select both
directions in
parameter 4-10 Motor Speed Direction . The function is not active in process closed loop.
[11] Start reversing Used for start/stop and for reversing on the same wire. Signals on start are not allowed at the same time.
[12] Enable start
forward Disengages the counterclockwise movement and allows clockwise direction.
[13] Enable start re-
verse Disengages the clockwise movement and allows counterclockwise direction.
[14] Jog (Default digital input 29): Activate jog speed. See parameter 3-11 Jog Speed [Hz] .
[15] Preset refer-
ence on Shifts between external reference and preset reference. It is assumed that [1] External/preset has been se-
lected in parameter 3-04 Reference Function . Logic 0 = external reference active; logic 1 = 1 of the 8 preset
references is active.
[16] Preset ref bit 0 Preset reference bit 0, 1, and 2 enable a choice between 1 of the 8 preset references according to table 9 .
[17] Preset ref bit 1 Same as [16] Preset ref bit 0 .
[18] Preset ref bit 2 Same as [16] Preset ref bit 0 .
Table 9: Preset Reference Bit
Preset ref. bit 2 1 0
Preset ref. 0 0 0 0
Preset ref. 1 0 0 1
Preset ref. 2 0 1 0
Preset ref. 3 0 1 1
Preset ref. 4 1 0 0
Preset ref. 5 1 0 1
Preset ref. 6 1 1 0
Preset ref. 7 1 1 1

Option Function
[19] Freeze
ref Freezes the actual reference, which is now the point of enable/condition to be used for
[21] Speed up
and
[22]
Speed down . If speed up/speed down is used, the 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 0–
parameter 3-03 Maximum Reference
.
