n033 : Motor Rated Current Factory setting: See Table A3-1
(Motor Rated FLA)
Range: see description
This parameter should be set, in increments of 0.1 A, to the rated current (FLA) value
shown on the motor nameplate; this value MUST BE between 10% and 120% of the drive
rated current (refer to Specifications in Appendices 2 & 3 of this manual). If the motor
FLA does not fall within this range, a different Model No. drive must be used.
NOTE: Setting n033 to " 0.0 " disables the motor overload protection
function, regardless of the setting of n034 .
n034: Electronic Thermal Motor Protection
(Motor OL Sel)
The drive protects against motor overload with a UL-recognized, built-in electronic thermal
overload relay.
The electronic thermal overload function monitors motor temperature, based on drive
output current and time, to protect the motor from overheating. When the electronic
thermal overload trips, an " oL1 Overload 1" error occurs, shutting OFF the drive output
and preventing excessive overheating of the motor.
When operating with one drive connected to only one motor, an external thermal relay is
not needed. When operating several motors with one drive, install a thermal overload relay
on each motor.
