Inverter capacity selection
(Sn-01)
•
The inverter capacity has already been set at factory according to the following
tables. Whenever the control board is replaced, the setting Sn-01 must be set again
according to the following tables.
•
Whenever the setting Sn-01 has been changed, the inverter system parameter
settings should be changed based upon the constant torque (CT) load (setting of Sn-
61= 0) or variable torque (VT) load (Sn-61= 1).
