<1> When terminal S5 is open, the motor rotates forward. When closed, the motor rotates in

reverse.

WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control

terminals and ensure parameter b1-17 is set to 0 (drive does not accept a run command at power up (default)).

If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence (default) and if parameter b1-17 is

set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction at power up of

the drive and may cause injury.

Note:

Refer to Parameter List on page 213

for a list of digital input functions. After performing a 3-Wire

initialization (A1-03 = “3”), the drive will automatically assign the forward/reverse command to terminal

S5.

Note:

Run by Turning on/off the Power Supply. For safety reasons, the drive is initially set up not to accept a

run command at power up (b1-17 = "0"). If a run command is issued at power up, the RUN indicator

LED will flash quickly. To change this and have the run command issued by the drive, change parameter

b1-17 to 1.

Stopping Method Selection: b1-03

When a Stop command is issued, the drive stops the motor using one of two possible methods.

n

Ramp to Stop: b1-03 = 0

When b1-03 = 0, the motor will decelerate to a stop when a stop command is entered. The

deceleration time is set by C1-02 (Deceleration Time 1).

Refer to Acceleration/Deceleration:

C1-01 to C1-04 on page 93

.

When the output frequency falls below E1-09 (Minimum Output Frequency) during

deceleration, the DC Injection braking current (b2-02) will be activated for the specified DC

Injection time at stop (b2-04).
