Example 5: Remote Sequence (3-Wire) & Speed Potentiometer
- vii -
This configuration is best when a person rather than an external controller (PLC, relay, etc.) controls the drive.
Both potentiometers ((R1) & (R2)) should have a resistance value between 2000
Ω
and 3000
Ω
and be rated for
at least 1 Watt. The trim pot is optional, but without it the manual speed pot will output 10V (60 Hz) at just
three-quarters of its rotation.
OPERATION:
•
Close pushbutton (PB1) momentarily while pushbutton (PB2) is closed and the drive will start.
Pushbutton (PB1) does NOT need to be maintained.
•
Open pushbutton (PB2) at any time and the drive will stop.
•
If switch (SW1) is open the drive will run in the forward direction. If switch (SW1) is closed, the drive will
run in the reverse direction. Switch (SW1) can be operated with the drive running at any speed.
•
Frequency reference is proportional to the signal level at Terminal FV.
0V = 0 Hz, 5V = 30 Hz, & 10V = 60 Hz.
•
If the drive is put in the “Local” mode using the LO/RE quick start LED, the drive will behave the same as
illustrated in Example 1.
Table 6: Programming Required For Remote 3-wire Sequence & Speed Pot Reference
Parameter Display Description
n001 11
The drive will perform a 3-wire reset.
CAUTION:
Setting this value will reset all parameters to their
original factory settings (all previous adjustments will be lost)
When the drive completes the reset, this parameter returns to a
value of 1.
n001 4 After doing the reset above, the password parameter returned to a
1. Change it to a 4 to get access to all parameters in the drive.
n036 Set Motor FLA Enter the motor’s full load amps as shown on motor nameplate.
After the programming is complete, the trim pot needs to be calibrated. Press DSPL until the FREF quick start
LED is illuminated. Turn the Speed Pot (R1) all the way up. Adjust the trim pot (R2) so that the “Frequency
Reference” display is just flickering between 59.99 Hz and 60.00 Hz. This completes the trim pot calibration.
