Parameter Descriptions
SPEED FBK %
This parameter changes according to the CONTROL MODE (DRIVE CONFIG function block):
 In CLOSED-LOOP VEC mode the parameter shows the mechanical speed of the motor shaft as a percentage of the user
maximum speed setting (MAX SPEED in the REFERENCE function block) as calculated from the motor speed feedback.
 In SENSORLESS VEC mode the parameter shows the calculated mechanical speed of the motor shaft as a percentage of
the user maximum speed setting (MAX SPEED in the REFERENCE function block).
 In VOLTS / Hz mode, the parameter shows the electrical drive output frequency as a percentage of the user maximum
speed setting (MAX SPEED in the REFERENCE function block).
 In PMAC control mode, the parameter shows the mechanical speed of the motor shaft.
TORQUE FEEDBACK
In PMAC Motor Control Mode, this shows the estimated motor torque as a percentage of the PERM TORQUE in the PMAC
MOTOR 1 function block.
FIELD FEEDBACK
Designed for all Motor Control Modes, except PMAC control mode (in PMAC Motor Control Mode, the value is always 0).
A value of 100% indicates the motor is operating at rated magnetic flux (field).
MOTOR CURRENT %
In PMAC Motor Control Mode, this diagnostic shows the level of rms line current being drawn from the drive as a
percentage of the PERM CURRENT in the MOTOR PMAC 1 function block.
MOTOR CURRENT A
In PMAC Motor Control Mode, this diagnostic shows the level of rms line current in Amps being drawn from the Drive.
STACK RATING A
This diagnostic indicates the stack rating in Amps. This reduces as a function of pwm switching frequency.
