Application Setup Examples
Function
Restore the adjustable frequency drive
1) Set motor parameters:
Set the motor parameters according to nameplate
data
Perform a full auto tune
2) Check that motor is running in the right direction.
When motor is connected to an adjustable frequency drive with straight forward phase order as U - U; V- V; W - W motor shaft usually
turns clockwise seen into shaft end.
Press ["Hand"]. Check shaft direction by applying a
manual reference.
If motor turns opposite of required direction:
1. Change motor direction in H-08 Reverse Lock
2. Turn off line power - wait for DC link to
discharge - switch two of the motor phases
Set configuration mode.
Set Local Mode Configuration
3) Set reference configuration, i.e. the range for reference handling. Set scaling of analog input in parameter AN-##
Set reference/feedback units
Set min. reference (50° F [10°C])
Set max. reference (176° F [80°C])
If set value is determined from a preset value
(array parameter), set other reference sources to
No Function.
4) Adjust limits for the adjustable frequency drive:
Set ramp times to an appropriate value as 20 s
Set min. speed limits
Set motor speed max. limit
Set max. output frequency
Set S201 or S202 to desired analog input function (Voltage (V) or milli-Amps (I))
NOTE! Switches are sensitive - Make a power cycling keeping default setting of V
5) Scale analog inputs used for reference and feedback
Set terminal 53 low voltage
Set terminal 53 high voltage
Set terminal 54 low feedback value
Set terminal 54 high feedback value
Set feedback source
6) Basic PID settings
Process PID Normal/Inverse
Process PID Anti Wind-up
Process PID start speed
Save parameters to keypad
