Option Function
The stop is performed according to the selected ramp time:
Parameter 3-42 Ramp 1 Ramp Down Time ,
Parameter 3-52 Ramp 2 Ramp Down Time ,
Parameter 3-62 Ramp 3 Ramp down Time , and
Parameter 3-72 Ramp 4 Ramp Down Time .
N O T I C E
When the drive is at the torque limit and has received a stop command, it may not stop by itself. To
ensure that the drive stops, configure a digital output to
[27] Torque limit and stop . Connect this digital
output to a digital input that is configured as coast.
[8] Start (Default digital input 18): Select start for a start/stop command. Logic 1 = start, logic 0 = stop.
[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
selected 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
284 .
[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 284: 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
