Terminal Description
X3.14 Operating The output is reset, when the heat sink is approx. 50°C warm.
Frequency For the next drive the operating frequency is reduced to 8 kHz.
Warning After cooling down (heat sink temperature approx. 40°C) the operating
frequency increases to 16 kHz and the output is set again.
! see operating frequency page GB 16 !
X3.15 Braking The output emits the signal applied on terminal X3.16.
Control
See description of terminal X2.8 regarding operating frequencies.
X3.17 Delay The output is set until the speed level LF.62 is gone below. The function only
Control works when the incremental encoder is connected and when the speed
controller is switched on (LF.30
≠
0).
X3.18 Crawl The output emits the applied signal on terminal X3.19. This is done until the
Speed preset speed level in parameter LF.63 is gone below. This function only
works when the incremental encoder is connected and the speed controller
is switched on (LF.30
≠
0).
X3.20 Main Contactor The ouput emits signals that are applied to terminal X3.21. The output
occurs,
Control when the following conditions are met at the same time:
- no error message is present
- setpoint must be selected
- the input contactor control must be activated
X3.22 DC-Voltage The output is set, when the dc-bus voltage exceeds the level LF.64.
Monitoring
X3.23
Motor
The output is reset, when the connection between the “OH” inputs is high-
Temperature resistant. This is how the lift control receives the message that the motor is
Warning overheating. It then can stop driving and let the motor cool down. If the
overheating continues, the inverter switches off, when the delay time set in
LF.65 has run out. The error signal “E-dOH” (Error, drive overheat) is
displayed. When the connection between the OH terminal is low resistant
again, the inverter shows the message “E.nOH” (no overheat). The error can
then be reset.
