Programming Guide
Option Function
[5] DC brake in- Inverted input for DC brake (NC). Stops motor by energizing it with a DC current for a certain time period.
verse
See parameter 2-01 DC Brake Current to parameter 2-03 DC Brake Cut In Speed [RPM]. The function is only
active when the value in parameter 2-02 DC Braking Time is different from 0. Logic 0⇒DC brake.
[6] Stop inverse
Stop inverted function. Generates a stop function when the selected terminal goes from logical level 1 to
logical level 0.
The stop is performed according to the selected ramp time:
•
•
•
•
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, bus, or LCP) 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 Disengages the counterclockwise movement and allows clockwise direction.
forward
[13] Enable start re- Disengages the clockwise movement and allows counterclockwise direction.
verse
[14] Jog (Default digital input 29): Activate jog speed. See parameter 3-11 Jog Speed [Hz].
[15] Preset refer- Shifts between external reference and preset reference. It is assumed that [1] External/preset has been
ence on
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
329.
[17] Preset ref bit 1
Same as [16] Preset ref bit 0.
[18] Preset ref bit 2
Same as [16] Preset ref bit 0.
