P2-15/P2-18 Relay outputs
The function of the relay outputs can be selected according to the table below. If a relay is controlled depending on a limit value, it reacts as follows:
|
Settings |
Function |
Explanation |
|---|---|---|
|
0 |
Inverter enabled |
Relay contact closed when the inverter is enabled. |
|
1 |
/Failure. Inverter ready |
Relay contact closed when inverter is operable (no error). |
|
2 |
Motor at setpoint speed |
Relay contact closed if output frequency = setpoint frequency (hysteresis P6-04). |
|
3 |
Motor speed ≥ 0 |
Relay contact closed if output frequency > speed 0 min-1 (hysteresis P6-04). |
|
4 |
Motor speed ≥ limit value |
Relay contact closed if the level is greater than or equal to the value set in parameter "Upper user relay limit/analog output". Relay contact open if the level is below the value set in parameter "Lower user relay limit/analog output". |
|
5 |
Motor current ≥ limit value | |
|
6 |
Motor torque ≥ limit value | |
|
7 |
Analog input 2 ≥ limit value | |
|
8 |
Hoist (for P2-18 only) |
This setting is made automatically if the hoist function is activated via P4-12. The inverter controls the relay according to the hoist function. |
|
9 |
STO status |
Relay contacts closed if STO circuit is supplied with 24 V. Relay contacts open if STO circuit is open (inverter indicates "inhibit"). |
|
10 |
PID error ≥ limit value |
Relay contact closed when the control error is greater than or equal to the value set in parameter "User relay upper limit". Relay contact open when the control error is less than the value set in parameter "User relay lower limit". The relay opens also with negative control errors. |
|
11 Only in connection with LTX. |
Drive referenced |
Relay contacts closed when the inverter is referenced. This option is available only with LTX servo module and only for the following inverters:
