and the 60 HZ switch determine the V/Hz ratio

to be delivered to the motor. The voltage on the

COASTCOAST

COAST - Selectable deceleration mode

for stop commands.

ONON

ON - The power to the DC bus is re-

moved immediately when a stop com-

mand is given. This causes the motor to

decelerate rapidly at a rate controlled by

the inertia of the load. Do not use this

setting for normal operation.

OFFOFF

OFF - The motor will be driven to a stop

at the deceleration rate determined by

SW1 switches D0, D1, and D2. See Sec-

tion 7.1.2.

REVERSEREVERSE

REVERSE - The direction of motor ro-

tation is determined by the position of this

switch. See Section 4.5.

ONON

ON - the REV LCD on the front panel is

illuminated and the motor rotation is op-

posite of the normal directional rotation.

OFFOFF

OFF - The motor rotation is as the wires

are connected to the drive output (for-

ward).

60 HZ - The output frequency of the

drive to be delivered to the motor at full speed is

determined by the 60 HERTZ switch. The speed

is calibrated by the MIN SPEED and MAX

SPEED potentiometers (see Section 6.1), but

the frequency (Hz) of the V/Hz ratio is set by

this switch
