1329I-5.5 Integrated Drive/Motor — January, 2000

To set the maximum speed:

1. To increase the maximum speed, turn the maximum speed rotary switch to a higher

position number.

-or-

To decrease the maximum speed, turn the maximum speed rotary switch to a lower
position number.

2. Connect the display board ribbon cable and replace the cover. Verify that all four

cover screws are in place and tightened.

3. Apply AC input power.

4. Set the operator’s speed reference signal to maximum.

Standard units: Use the speed potentiometer or other user-supplied external speed
reference device.

Local operator control units: Use the

key to increase the speed reference and the

key to decrease the speed reference.

5. Use a hand held tachometer to monitor motor speed.

6. Repeat the adjustment procedure until the desired maximum speed is obtained.

Note that changes to the maximum speed setting are recognized only while the
drive is stopped.

Important:

If speed is erratic or not as expected, verify that only one of the speed reference
inputs (0 to 10 VDC or 4 to 20 mA) has been wired.

Adjusting the Acceleration / Deceleration Time

The acceleration / deceleration time is the amount of time it takes the motor to ramp
from stop to the maximum speed setting of the unit. This is also the amount of time it
takes the motor to ramp from the maximum speed setting to stop. For all settings except
Setting 0, Acceleration time is equal to Deceleration time.

Range: 1, 5, 10, 15, 20, 30, 60, 90 seconds

Default: 5 seconds

0 = 1 Second Accel/5 Sec Decel
1 = 5 Seconds (Default)
2 = 10 Seconds
3 = 15 Seconds
4 = 20 Seconds
5 = 30 Seconds
6 = 60 Seconds
