KEYPAD SETUP
Keypad Stop Key Allows keypad STOP key to initiate motor stop during remote or
serial operation (if set to Remote ON). Pressing STOP initiates the stop
command and automatically selects Local mode.
Keypad Stop Mode Causes the motor to coast to a stop or regen to a stop for a stop
command. In coast, the motor is turned off and allowed to coast to a stop. In
regen, the voltage and frequency to the motor is reduced at a rate set by the
decel time.
Keypad Run FWD ON makes the keypad FWD key active in Local.
Keypad Run REV ON makes the keypad REV key active in Local.
Keypad Jog FWD ON makes the keypad FWD key active in Local Jog.
Keypad Jog REV ON makes the keypad REV key active in Local Jog.
Switch On Fly ON allows switching from Local to Remote mode or back without
stopping the drive.
Loc. Hot Start ON allows the stop input to be used in keypad mode.
V/HZ AND BOOST
CTRL Base FREQ Represents the point on the V/Hz profile where output voltage
becomes constant with increasing output frequency. This is the point at which
the motor changes from constant or variable torque to constant horsepower
operation. In some cases the Max Output Volts and CTRL Base Freq values can
be manipulated to provide a wider constant torque or wider constant horsepower
speed range than is normally available with the motor.
Torque Boost Adjusts the amount of motor starting torque. The boost adjustment
alters the output voltage to the motor from the normal voltage value by
increasing or decreasing the starting voltage by fixed values as defined by the
V/Hz profile. The factory setting is suitable for most applications. Increasing the
boost may cause the motor to overheat. If adjustment is required, increase the
boost in small increments until the motor shaft just starts to rotate with maximum
load applied.
Slip Comp Adjustment Compensates for varying load conditions during normal
operation. This parameter sets the maximum allowable variation in output
frequency under varying load conditions (changes of output current). As motor
current increases toward 100% of Motor Rated Amps, output frequency is
automatically increased to compensate for slip.
V/Hz Profile Sets the Volts/Frequency ratio of the control output (to the motor) for all
values of output voltage versus output frequency up to the control base
frequency. Because motor voltage is related to motor current, motor voltage can
then be related to motor torque. A change in the V/Hz profile can adjust how
much torque is available from the motor at various speeds.
3PT profile - allows two linear V/Hz segments by setting the V/Hz 3PT Volts and
V/Hz 3PT Frequency parameters. 0% to 100% squared reduced may be
selected for the V/Hz profile. (0% = Linear V/Hz Profile.)
These profiles are shown in Figure 4-3.
