[100% Torq Vel]
Motor velocity at 100% rated motor torque.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".
Parameter Numbers 392

Linkable No
Minimum Value 1 rpm
Maximum Value 8000 rpm
Default Value This is determined by the motor catalog number.
[300%Torq Vel]
Motor velocity at 300% rated motor torque.
Note: Before making modifications to Mtr Data
parameters, [Motor Type] must be set to "custom
motor".
Parameter Numbers 388

Minimum Value 1 rpm
Maximum Value 8000 rpm
Default Value This is determined by the motor catalog number.
[Anlg Vel Ofst]
An offset value that can be used on an analog
velocity input to counter voltage offsets on that
input. This value is added after the input scaling
has taken place, therefore changing the analog
input scaling will change this offset
compensation.

[Anlg Vel Scal]
Use this parameter to determine how the A/D
converter value is scaled. It is set to the number
of motor rpm that is to represent 1 volt of input
command. The desired input velocity command
voltage to motor rpm scaling is accomplished
with this parameter. The default setting is 500
rpm/volt. Use the following formula if the
maximum motor speed (rpm) and maximum
velocity command (volts) are known.

[ATune Current]
The motor current used while an auto tune cycle
is executing is specified with this parameter. In
most cases, the default setting will be
satisfactory.
