Maintenance parameters

2.11.3 Motor primary resistance (Pr. 99 )

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.

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
99	Motor primary	- - -	0 to 50Ω,	Setting is enabled when Pr. 30 = "1"
	resistance		- - -

2.12 Maintenance parameters

2.12.1 Maintenance output function (H1 , H2 )

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.)

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
H1 (503)	Maintenance timer	0	0 to 999 Write disabled		Setting can be
H2 (504)	Maintenance alarm	36	0 to 999, - - -	- - -: Function as	made when Pr.
	output set time	(36000h)		36000h	30 = "1"

The parameter numbers in parentheses are those for use with the parameter unit (FR- PU04).
