Stop-On-Contact Control - Mitsubishi Electric FR-A800 Series Instruction Manual

Confirming the starting times can be used to determine the timing of the maintenance, or can be used as a reference for system
inspection or parts replacement.

• Every start signal input (the RUN signal ON) while the inverter output is stopped is counted as the inverter starting time.
(Starting during pre-excitation is also counted.)

• The lower four digits of the number of starting times is displayed in Pr.1410 Starting times lower 4 digits, and the upper
four digits of the number of starting times is displayed in Pr.1411 Starting times upper 4 digits.
• The maximum count is "99999999". When "99999999" is exceeded on the monitor, the monitor value is reset to 0.

NOTE
• Any value can be set in Pr.1410 or Pr.1411. Set "0" to clear the number on the monitor.
• Starting during offline auto tuning is not counted.
• Under position control, the count increases when the LX signal turns ON.
• The counting is enabled even if the RUN signal is not assigned to an output terminal.
• For the RUN signal, refer to
• Starting during the test operation (Pr.800 = "9") is not counted.

To ensure accurate positioning at the upper limit, etc. of a lift, stop-on-contact control causes the mechanical brake to close
while the motor creates a holding torque to keep the load in contact with a mechanical stopper, etc.
This function suppresses vibration that is likely to occur when the load is stopped upon contact in lift applications, thereby
ensuring reliable and highly accurate positioning stop.
