P16 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.
