Motor Data
45 [Max Ref Speed]
Highest speed reference that can be commanded. The value of this parameter
also scales external speed reference values (rpm) to internal units (counts),
including analog inputs (10V = Par 45 rpm). Rated motor speed is
determined via Par 456 [Fld Weaken Ratio] when field weakening is used. If
field weakening is not used, set this parameter to the motor base speed.
Notes: If a speed feedback device is used (encoder, resolver, or tachometer),
see Drive Reference and Feedback Scaling on page 265
for instructions. The
maximum value was changed from “16383” for firmware version 3.001.

162 [Max Feedback Spd]
Specifies the scaling between internal (counts) and external speed feedback
values. Typically, this parameter is set to the same value as Parameter 45
[Max Ref Speed]. If an analog (DC) tachometer is used, this parameter's value
must be set to be compatible with the S4 switches on the control board (see
DIP Switch and Jumper Settings on page 72
). If armature voltage feedback is
used, this parameter must be set to the motor nameplate base speed. Par 585
[Overspeed Val] should be set 10% higher than the value entered into Par
162. Rated motor speed is determined via Par 456 [Fld Weaken Ratio] when
field weakening is used. If field weakening is not used, set this parameter to
the motor base speed.
Notes: If a speed feedback device is used (encoder, resolver, or tachometer),
see Drive Reference and Feedback Scaling on page 265
for instructions. The
maximum value was changed from “16383” for firmware version 3.001.

175 [Rated Motor Volt]
Maximum armature voltage of the drive. Typically, this value is set to the
Motor Nameplate Armature voltage. When Par 469 [Field Mode Sel] is set to 1
= “Field Weaken”, the value in this parameter equals the voltage at which the
field weakening phase begins.
Note: This parameter affects the threshold of an overvoltage condition, as
indicated by an “Arm Overvoltage” fault (F5).

179 [Nom Mtr Arm Amps]

and the overload function are based on this current value. Also, this value
should be greater than 1/3 the value of Par 465 [Drive Size].
