Example 2
The variable selector can also be used to select between two modes of operation of an unprotected parameter of the drive
e.g. parameter
1.14
reference select
Set-up
1.22

Preset speed 2 to 0.4

Preset speed 3 to 0.1

12.08
=

Operation
When either the run forward or run reverse terminal is closed allowing the drive to run, keypad mode is selected. This allows
the drive’s speed to be increased or decreased via the drive’s up and down buttons on the drive’s keypad. The drive can also
be stop or started via the drive’s keypad.
If the drive is running and either the run forward or run reverse terminal is opened, the drive will stop as keypad mode is de-
selected and terminal mode selected.
Parameter 1.14 was only unprotected in V01.08.00 software.
To change between other different modes of parameter

12.18 Analog input trim
The following set-up allows analog input 1 to be used as the main speed reference and analog input 2 as an offset trim of the
main reference.
Example 1
1.21 =
500
Preset speed 1 to 500. This will give an error between PID reference source and PID feedback
7.10 =
0
Analog input 1 destination to zero
7.14 = 0
Analog input 2 destination to zero
14.02 = 7.01
PID main reference source to analog input 1 percentage
14.03 = 7.02
PID reference source to analog input 2 percentage
14.04 = 1.21
PID feedback source to preset speed 1
14.08 =
1
PID enabled
14.11 =
0
PID integral gain to zero
14.13 =
25
PID high limit to 25
14.14 =
-25
PID low limit to -25
14.16 = 1.36
PID output to analog reference 1
Perform a Save routine:
xx.00
= 1000 and press red Stop / Reset button on the drive
Operation
With the above set-up, analog reference 1 can be used as normal to control the speed of the motor. Analog reference 2 can
be used to increase or decrease (trim) this speed around analog reference 1. With this set-up the trim will be approx. ±12.5Hz
around analog reference 1. Parameter
14.13
and
14.14
can be increased or decreased to give larger or smaller trim value.
One problem with the above set-up is if maximum trim is set on analog reference 2 with zero speed reference on analog ref-
erence 1, the drive will run at maximum trim speed and not go to zero speed. If the motor is required to go to zero speed with
zero reference, the following set-up should be used.
