UNITS EDITING
This allows parameter and keypad speed editing in whole units or tenths of units above 100. Below 100,
the value can always be changed by tenths of units.
01
TENTHS OF UNITS: The value can always be changed by tenths of units (up to a value of
1000). If the
▲ or ▼ button is pressed and held, the value will change by tenths of units until
the next whole unit is reached, and then the value will change by whole units. Refer to Section
13.1.
02
WHOLE UNITS: The value can be changed by tenths of units until 99.9 is reached. Above
99.9, the value will change in whole unit increments only. Below a value of 100, if the
▲ or ▼
button is pressed and held, the value will change by tenths of units until the next whole unit is
reached, and then the value will change by whole units.
P17
ROTATION DIRECTION
01
FORWARD ONLY: The drive will only allow rotation in the forward direction. However, JOG
REVERSE (see Parameter 11) will still operate even if FORWARD ONLY is selected.
02
FORWARD AND REVERSE: The drive will allow rotation in both directions.
P19
ACCELERATION TIME
This parameter sets the acceleration rate for all of the speed reference sources (keypad, speed pot, 4-20
mA, 0-10 VDC, jog, MOP, and preset speeds). This setting is the time to accelerate from 0 Hz to the
BASE FREQUENCY (Parameter 27).
P20
DECELERATION TIME
This parameter sets the deceleration rate for all of the speed reference sources (keypad, speed pot, 4-20
mA, 0-10 VDC, jog MOP, and preset speeds). This setting is the time to decelerate from BASE
FREQUENCY to 0 Hz.. If the drive is set for COAST TO STOP (setting 01 or 02 in Parameter 04),
this parameter will have no effect when a STOP command is given.
P21
DC BRAKE TIME
This determines the length of time that the DC braking voltage is applied to the motor. The DC BRAKE
TIME should be set to the lowest value that provides satisfactory operation in order to minimize motor
heating.
