Level 1 Parameter Definitions
as follows:
Description
Represents the absolute motor speed where 0VDC = 0 RPM and
+5VDC = MAX RPM.
Represents the absolute value of torque where
+5VDC = Torque at CURRENT LIMIT.
+5VDC = MAX RPM.
+5VDC = MAX AC Voltage.
Represents the actual portion of total current used for excitation.
5VDC= MAX flux current.
5VDC= MAX commanded flux current.
(CW and CCW torque).
5V = Max. CW torque, 0V = Max. CCW torque.
5V = Max. commanded load current.
5VDC = Rated Current.
current. 5VDC = Rated Current.
A scaled AC waveform that represents the AC line to line motor
terminal voltage. 0V = Neg Peak PWM voltage. 2.5V centered.
5V = Pos Peak PWM voltage. At rated motor voltage, a full 0 to 5V
sinusoidal waveform should be present. This waveform should be at
or greater than the motor base frequency. (At half the motor base
frequency, a 1.25V to 3.75 sine wave is present.)
Bus voltage scaled to 0-5VDC. 5V = 1000VDC.
Bipolar torque output. 2.5V centered, 5V = Max Positive Torque,
0V = Max negative torque.
Bipolar power output. 2.5V = Zero Power, 0V = negative rated peak
power, +5V = Positive rated peak power.
Represents motor speed scaled to 0V = negative max RPM,
+2.5V = Zero Speed, +5V = positive max RPM.

(Accumulated current) x (time), Overload occurs at +5V.
0V = negative rated peak amps, +5V = positive rated peak amps.
0V = negative rated peak amps, +5V = positive rated peak amps.
2.5V centered, 5V = 100%, 0V = –100%.
Position within a single revolution. +5V = 1 complete revolution.
The counter will reset to 0 every revolution.
2.5V centered, 5V = 100%, 0V = –100%.
