Option REL
Inverters which are equipped with the REL option possess relay outputs instead of the two
open-collector outputs. Programming is performed by way of the functions OC1 and OC2.
Sign + : The relay picks up at condition.
Sign - : The relay drops out at condition.
code
0: Motor speed greather than FX1 (TAB1, function U).
1: Motor speed greather than FX2 (TAB1, function u).
2: Motor has reached the end of the ramp. Indication at 0Hz included.
3: Motor speed = 0 Hz.
4: Motor speed = 0 Hz. Message at the end of the torque holding time
(see TAB1, function 9).
5: Output current threshold exceeded (TAB1, SUB IMOT, function S).
6: Output current threshold exceeded; message at the end of the programmed
delay time (TAB1, SUB IMOT, function DY).
7: +: Relay picks up when motor rotates in counter-clockwise direction (CCW).
- : Relay drops out when motor rotates in clockwise direction (CW).
8: The dynamic braking power is near the programmed limit
(TAB2, function BrLim).
9: Motor has reached the end of the ramp. Indication at 0Hz excluded.
10:The inverter (heat sink) temperature reaches the limit value.
(Only with Softw. D2A-STD).
11:The motor temperature reaches the limit value.
(Only with ACM D2 30.0 - 37.0 kW and Softw. D2A-STD).
