Selection (Value)
Preset Value: 0
Range: 0 - 3
Sets the PWM operating zone to Standard 2.5kHz output carrier frequency
Std Const Trq (0) Constant Torque. Constant Torque allows 175% for 3 seconds and 150% for
60 seconds of peak overload capacity.
Sets the PWM operating zone to Standard 2.5kHz output carrier frequency
Std Var Trq (1) Variable Torque. Variable Torque allows 125% for 1 second and 115% for 60
seconds of peak overload capacity.
Sets the PWM operating zone to Quiet 8.0kHz output carrier frequency
Quiet Const Trq (2) Constant Torque. Constant Torque allows 175% for 3 seconds and 150% for
60 seconds of peak overload capacity.
Sets the PWM operating zone to Quiet 8.0kHz output carrier frequency
Quiet Var Trq (3) Variable Torque. Variable Torque allows 125% for 1 second and 115% for 60
seconds of peak overload capacity.
Preset Value: 0
Range: 0 - MAX Speed RPM
Sets the minimum motor speed in RPM. During operation, the motor speed
will not decrease below this value except for motor starts or during dynamic
braking to a stop.
Preset Value: Rated Motor Speed
Range: 30 - 15,000 RPM
Sets the maximum motor speed in RPM.
Preset Value: 2500
Range: 1500 - 16000 Hz
The frequency that the output transistors are switched. PWM (pulse width
modulation) frequency is also referred to as "Carrier" frequency. PWM should
be as low as possible to minimize stress on the output transistors and motor
windings. It is recommended that the PWM frequency be set to approximately
15 times the maximum output frequency of the control. Ratios less than 15
will result in non-Sinusoidal current waveforms.
Preset Value: 0.004
Range: 0.000 - 10.000 seconds
Limits the rate of torque change in response to a torque command. This
parameter sets the time in seconds to change the output torque by 1 times
motor rated torque.
Preset Value: CALC
Range: 0 - Peak Rated Current
(Vector) Sets maximum motor current level for operation.
(V/F) Sets the motor current (including MAG current) where foldback begins.
Preset Value: CALC
Range: 0.0 - Drive Rated Peak Current in amps
Sets the maximum motor current (not including MAG current allowed during
regen. Based upon brake resistor ohms programmed in P2501.
Preset Value: 0
Range: 0 - 500 Hz/Sec
Used to increase the drive output frequency to the motor when regen current
is greater than 1/10th of current limit to avoid overvoltages when applying the
drive with cyclic regenerative loads such as pump jacks.
