indicates simple mode parameters and indicates extended parameters. When setting parameters, refer to the instruction manual (applied) and understand instructions. Pr. Pr.
When the RS-485 terminals or communication option is used,
the external operation command and speed command can be
made valid. Also, the control command source in the PU
operation mode can be selected.
* Pr. 550 and Pr. 551 are always write-enabled.
You can utilize the on/off of the inverter's output signals instead
of the remote output terminal of the programmable logic
controller.
When the cumulative energization time of the inverter reaches
the parameter set time, the maintenance timer output signal
(Y95) is output.
(MT) is displayed on the operation panel
(FR-DU07)
This can be used as a guideline for the maintenance time of
peripheral devices.
The cumulative energization time of the inverter is stored into the
EEPROM every hour and indicated in Pr. 503 Maintenance timer in
100h increments. Pr. 503 is clamped at 9998 (999800h).
The average value of the output current during constant speed
operation and the maintenance timer value are output as a pulse to
the current average value monitor signal (Y93).
The pulse width output to the I/O module of the PLC or the like can
be used as a guideline due to abrasion of machines and elongation
of belt and for aged deterioration of devices to know the
maintenance time.
The current average value monitor signal (Y93) is output as
pulse for 20s as 1 cycle and repeatedly output during constant
speed operation.
