1.4.22 Maintenance timer alarm signal (Y95)
(common)
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).
When the [
Pr. 503
] setting reaches the time set in [
Pr. 504
Maintenance timer alarm output set time ] (100h increments),
the maintenance timer alarm output signal (Y95) is output.
For the terminal used for the Y95 signal output, assign the
function by setting 95 (positive logic) or 195 (negative
logic) in any of [
Pr. 190 to Pr. 196 Output terminal function
selection ].
*1 The cumulative energization time is counted every hour.
The energization time of less than 1h is not counted.
