P14 CONTROL
Parameter P14 selects the source of START/STOP and direction commands.
01
TERMINAL STRIP ONLY: The drive will only respond to START/STOP and direction commands
from the terminal strip.
02
REMOTE KEYPAD ONLY: The drive will only respond to START/STOP and direction commands
from the optional remote keypad. Terminals 13B and 13E must also be set for the REMOTE
KEYPAD option (refer to Parameters 12 and 13).
P16
UNITS EDITING
P16 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 p or q 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 4.2.1,
Setting Values in Tenths of Units Above 100.
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 p or q 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.
P18
MOTOR OVERLOAD TYPE
01
SPEED COMPENSATION: reduces the allowable continuous current when operating below 30Hz.
(01 = the default value per UL508C requirements). (Graph: Ir: rated current; f: motor frequency)

02
NO SPEED COMPENSATION: allows 100% of rated current at any speed. This setting should
only be used in applications where the motor is properly cooled at all speeds or the motor
manufacturer has approved the motor for use at full load operation at low speed.
P19
ACCELERATION TIME
P19 sets the acceleration rate for all of the speed reference sources (keypad, speed pot, jog, MOP, and
preset speeds). This setting is the time to accelerate from 0 Hz to the BASE FREQUENCY (Parameter 27).
