Unit Description / Notes
Additional Notes about the Digital Output Functions:
- Remote: Inverter is operating in Remote mode.
- Run: Inverter is enabled (the IGBTs are switching, the motor may be at
any speed, including zero).
- Ready: Inverter neither is in fault non in undervoltage condition.
- No Fault: Inverter is not in any fault condition.
- With Error means that the inverter is disabled due to some error.
- No E00: Inverter is not in an E00 fault condition.
- No E01+E02+E03: Inverter is not in an E01 or E02 or E03 fault condition.
- No E04: Inverter is not in an E04 fault condition.
- No E05: Inverter is not in an E05 fault condition.
- 4 to 20 mA OK: If applicable, the 4 to 20 mA current reference is
present.
- Zero Speed: Motor speed is lower than the value set at P291 (Zero
Speed Zone)
- Not Used: Digital Output remains inactive.
- Forward: Motor is running forward.
- Torque > Tx and Torque < Tx: Valid only for P202 = 3 or 4 (Vector
Control).
Torque corresponds to motor Torque as indicated in Parameter P009.
- Ride-Through: means that the inverter is executing the Ride-Through
function.
- Pre-charge OK: means that the DC-Link voltage is higher than the pre-
charge voltage level.
- Fieldbus: allows changing the state of the digital outputs (P275 to
P280) from the Fieldbus network. Refer to item 8.12.7.
- N > Nx and Nt > Nx: (this option works only for P202 = 4 - Vector with
Encoder Control) means that both conditions must be satisfied in order
that DOx = Saturated Transistor and/or RLx = relay picked up. The
Digital Outputs will come back to its OFF state, that is, DOx = Cut-off
Transistor and/or RLx = released relay, when only N>Nx condition is
not satisfied (that is, independent of Nt>Nx condition).
- Timer: These times enable and disable the relays 2 and 3 (refer P283
to P286).
- Brake (Vel) – Real Speed
It uses the Real Speed in the comparison of N > Nx to activate the
brake.
Note: Nx is programmable at P288.
- Brake (Ref) – Total Reference
If P202 = 3 (Sensorless Control) – It uses the Total Reference in the
comparison of N* > Nx to activate the brake.
