Waiting Time Setting At Mc Switchover (Pr.580, Pr.581); Acceleration/Deceleration Time When An Auxiliary Motor Is Connected And Disconnected (Pr.582, Pr.583); Starting Auxiliary Motors (Pr.584 To Pr.586, Pr.590); Stopping Auxiliary Motors (Pr.587 To Pr.589, Pr.591) - Mitsubishi Electric FR-F800 Instruction Manual

Waiting time setting at MC switchover (Pr.580, Pr.581)
• Set a waiting time for switchover of MC for the direct system (Pr.579="2") or alternative direct system (Pr.579="3").
• Set the MC switching time (for example, the time after RIO1 turns OFF until RO1 turns ON) in Pr.580 MC switching
interlock time.
• Set the time after the MC switchover until the motor starts (for example, the time after RIO1 turns OFF and RIO2 turns ON
until the inverter output starts) in Pr.581 Start waiting time. Set this time a little longer than the MC switching time.
Acceleration/deceleration time when an auxiliary motor is connected
and disconnected (Pr.582, Pr.583)
• Use Pr.582 Auxiliary motor connection-time deceleration time to set the deceleration time for forcibly decreasing the
output frequency of the inverter when an auxiliary motor connection occurs. Set the deceleration time in Pr.582 from Pr.20
Acceleration/deceleration reference frequency to stop. The output frequency is not forcibly changed when
Pr.582="9999".
• Use Pr.583 Auxiliary motor disconnection-time acceleration time to set the acceleration time for forcibly increasing the
output frequency of the inverter when an auxiliary motor disconnection occurs. Set the acceleration time in Pr.583 from stop
to Pr.20 Acceleration/deceleration reference frequency. The output frequency is not forcibly changed when
Pr.583="9999".
Starting auxiliary motors (Pr.584 to Pr.586, Pr.590)
• Use Pr.584 to Pr.586 to set the output frequency of the inverter at which the commercial power supply operation motors are
started. When output frequency equals to or higher than the setting continues for longer than the time set in Pr.590
Auxiliary motor start detection time, auxiliary motors driven by the commercial power supply are started.
• To set the starting frequency, use Pr.584 Auxiliary motor 1 starting frequency for the first auxiliary motor, and use Pr.585
Auxiliary motor 2 starting frequency for the second motor, and use Pr.586 Auxiliary motor 3 starting frequency for the
third motor.
• The starting sequence depends on the Pr.579 Motor connection function selection setting.
Stopping auxiliary motors (Pr.587 to Pr.589, Pr.591)
• Use Pr.587 to Pr.589 to set the output frequency of the inverter at which the commercial power supply operation motors are
stopped. When output frequency equals to or lower than the setting continues for longer than the time set in Pr.591
Auxiliary motor stop detection time, auxiliary motors driven by the commercial power supply are stopped.
• To set the stopping frequency, use Pr.587 Auxiliary motor 1 stopping frequency for the first auxiliary motor, and use
Pr.588 Auxiliary motor 2 stopping frequency for the second motor, and use Pr.589 Auxiliary motor 3 stopping
frequency for the third motor.
• The stopping sequence depends on the Pr.579 Motor connection function selection setting.
