7.1.2 Warnings and Group Errors
Message Cause / Remedy
Checking voltage Main voltage not yet applied.
Checking line Option 1: Main voltage is applied but the motor has not yet been connected or has been incorrectly connected.
Option 2: The motor is properly connected but there is no phase voltage.
Ready to start Device is ready to start (main voltage is applied and the motor is properly connected).
The motor will start as soon as a start command is received.
Start mode active Motor is started in the set starting mode.
Running Device is in bridging mode (bypass contactor). Starting completed.
Stopping mode active Motor is stopped using the set stopping mode.
Cooling down period of the motor
is active (for product version <
*E06* devices)
After overload tripping of the thermal motor model, it is impossible to start the motor for a defined period of time
(parameter: pre-charge time) to ensure that the motor can cool down.
Contact block cooling down
period
(for product version < *E06*
devices)
After overload tripping of the inherent protection, it is impossible to start the motor for 30 s to allow the device to
cool down.
Emergency start active The Emergency start function is activated.
Quick stop active The Quick stop function is activated.
Message
Warning
Error without restart
Error with restart
Cause / Remedy
No main power x 1. Start command output even though the main voltage has not yet been applied.
Remedy: Switch on main power.
2. If this message is issued in bypass operation, it may have been mistakenly issued because
one of the following messages was generated too often: "Prewarning motor temp.",
"Prewarning time" or "Current limit exceeded/undershot" (can also be traced via the entries
in Log list / Events).
Remedy: See the description of the respective messages
Incorrect start conditions (for product
version < *E04* devices)
Phase angle control failure (for product
version ≥ *E04* devices)
x 1. Error occurs without motor starting.
Cause:
- Motor has not been connected correctly.
- Inside delta circuit incorrectly configured.
- Ground fault present.
Remedy: Check and rectify wiring (see inside delta circuit wiring suggestions).
2. Error occurs during starting.
Cause:
- Start voltage too high
- Breakaway pulse set (incorrectly): instable motor start
(Only set breakaway pulse if absolutely necessary. In the case of pumps, for example ,a
breakaway pulse can often cause misfiring.)
If there is an idle time of < 5 s since the last start, the 3RW44 starts with a higher start
voltage. In combination with a set breakaway pulse, this can lead to "Incorrect start
conditions".
Remedy: Adjust parameters or increase idle time.
