Maximum value:
The output can be scaled to give a lower current
than 20 mA at full scale or 20 mA at an output
below 100% of the maximum signal value.
If 20 mA is the desired output current at a value
between 0 - 100% of the full-scale output, program the
percentage value in the parameter, i.e. 50% = 20 mA.
If a current between 4 and 20 mA is desired at
maximum output (100%), the percentage value to
program in the drive is calculated as:
,
i.e.
A similar scaling is possible on the pulse output.
The value (pulse scale value) in parameter 320
(output 42) and 321 (output 45) is the basis of
the scaling. If the pulse scale value is the desired
output at a value between 0 - 100% of the full
scale output, program the percentage, i.e. 50%
for pulse scale value at 50% output.
If a pulse frequency between 0,2 x pulse scale
value and pulse scale value, the percentage
is calculated as follows:
361 Encoder loss threshold
(ENCODER MAX ERR.)
Value:
0 - 600%
✭ 300%
Function:
This parameter adjusts the threshold level for detection
of encoder loss in speed closed loop mode. The value
equals a percentage of the nominal slip of the motor.
Description of choice:
Set the desired threshold level.
✭ = factory setting. () = display text [] = value for use in communication via serial communication port
