6–10 MM300 MOTOR MANAGEMENT SYSTEM – INSTRUCTION MANUAL
CONFIGURATION SETPOINTS CHAPTER 6: SETPOINTS
Forced starts (for example, external start) operate in the same fashion as other starts, with
the B contactor not calling for the inverter to ramp until the pre-contactor timer times out.
If up-to-speed feedback is not received from the inverter via the contactor B status within
the setpoint during a start, a Drive Start Failed alarm is generated. If up to speed feedback
resets before a stop control, an Inverter Fail alarm is generated, and the contactor B relay
opened. If inverter speed feedback remains when the
Ramp Down Time expires during a
stop, a Drive Stop Fail alarm is generated. Neither results in a trip or a stop. The Drive Start
Failed alarm is latched until reset. The Inverter Fail alarm is also cleared by a stop control.
The B Open Contactor Control Circuit and B Welded Contactor alarms implemented in the
start/stop control element are defeated when the inverter starter is selected.
If the inverter does not provide an up to speed feedback signal, the contactor B relay
contact or an auxiliary contact of the B contactor should be connected to the contactor B
status contact input to suppress spurious Drive Failed To Start alarms.
The Undervoltage Autorestart feature is disabled for the Inverter Starter.
The following figure illustrates typical starter timing beginning from the stopped state.
Figure 8: Typical starter timing for the inverter starter
The following additional setpoints are available for the inverter starter.
Pre-Contactor Time
Range: 0 to 60 seconds in steps of 1
Default: 0 seconds
This setpoint specifies the time after a start command before the motor is started. Most
starters do not use this delay for forced starts such as external start. This setpoint is also
used by the inverter starter and the soft start starter to set the amount of time between
powering up an inverter or soft starter and sending the ramp-up command. An audible
or other warning signal can be activated in this interval by connecting the signal to a
contact output set to the pre-contactor function.
Ramp Up Time
Range: 0 to 125 seconds in steps of 1
Default: 1second
This setpoint specifies the time after signalling the inverter starter to ramp up that the
up-to-speed feedback can be delayed without issuing a Drive Start Fail alarm.
