6.2.1 Reverse Plugging
When opposite drive command is active while the inverter is operating, the deceleration/acceleration
ramp can be shorter than the normal ramp. Reverse plugging function is “on” if the driving frequency >
30% of the “Max Freq” (not the “Motor Nom Freq”). Reverse plugging function goes “off state” in opposite
direction to original direction when driving frequency > 95% of reference frequency.
The value can be set between 50 to 100%. 100% corresponds that the ramp is the same as the normal
ramp. 50% corresponds that the ramp is a half of the normal ramp. The default value is 80%.
6.2.2 Relay output
Inverter has one programmable relay output (ROA1) and one relay output for brake control (ROD1).
Relay output functions for ROA1 are listed below.
Par value Name Description
0 Not Used
1 Fault Relay is activated when fault is on.
2 Brake Control External brake ON/OFF-control. Default value in relay output ROD1
(K7 control).
3 Run Relay is activated when current is fed to motor.
4 Ready Relay is activated when Drive is ready to operate.
5 Ready Inverted Relay is activated when Drive is not ready to operate.
6 Fan Relay is activated when DC-link voltage is above braking chopper operating level - 70V.
Relay is closed for a minimum of 300s.
7 Emergency Stop Relay is activated in case of F1 Overcurrent, F2 Overvoltage or F3 Earth Fault. Relay is
deactivated when the power is switched off.
8 Reverse Plugging Relay is activated when direction requested is different than direction of actual frequency.
9 At Speed Relay is activated when ramp generator output has reached speed reference request.
10 S2 Active Relay is activated when motor actual speed direction is S2.
11 Temp 1 Relay contact is activated when temperature is 20 °C (68F) or below. Relay is inactivate when
temperature is 23 °C (73F) or above.
12 Temp 2 Relay contact is activated when temperature is 40 °C (104F) or above. Relay is inactivate
when temperature is 37 °C (98F) or below.
