The parameter numbers in parentheses are those for use with the parameter unit (FR-
PU04).
<Setting>
Generally this parameter need not be set. At the factory setting of "- - -", the
standard motor constant of the motor capacity set in Pr. 98 (including that of the
constant-torque motor) is used.

The maintenance timer alarm signal (Y95) is output when the cumulative
energization time (H1 "maintenance timer") of the inverter reaches the time set
in H2 "maintenance alarm output set time". (Used to alert the operator of the
main circuit smoothing capacitor life expiration, for example.)
