Example 2
Because the Commander SE does not have an offset trim parameter, in order to achieve this function the drive's internal PID
loop must be used. In this example the analog output must read 5.5V on terminal 6 when the drive is reading 0Hz and then
proceed linearly to give 10V out on terminal 6 when the drive is at maximum speed.
Parameter set up
1.28 = 550.0
14.03 = 2.01
14.02 = 1.28
14.10 = 1.00
14.11 = 0
14.12 = 0
14.13 = 100% Allows the whole reference to pass through to the scaler
14.14 = 0
14.15 = 0.45
14.16 = 1.27
7.33 = prog
7.19 = 1.27
14.08 = 1
Perform a Save routine: xx.00 = 1000 and press red Stop / Reset button on the drive
This set up gives:
0Hz = 5.5V
50 Hz = 10V

Commander SE Advanced User Guide
Issue Number: 4
Offset using preset speed 8 calculated by:
Required voltage level @ 0Hz / Maximum voltage value of analog output x 1000 (Range of 1.28)
PID reference source assigned to post ramp frequency
PID main reference source assigned to preset speed 8
PID proportional gain
PID integral gain
PID derivative gain
PID output can never go negative
Scales the reference to 45%
PID output destination assigned to preset speed 7
Allows the user to assign the analog output to any programmable parameter
Programs the analog output to look at the PID output which is also programmed to this parameter (1.27).
