Parameters
mA I/O Parameters (P200 - P220)
These parameters are specific to the use of the mA output. Refer to mA Output on
page 91 for details.
• mA output 1 is physically located at terminals 21/22 on the main board
• mA outputs 2 and 3, and inputs 1 and 2 are physically located on the optional mA I/O
board which is mounted onto the main board.
In the case of assigning mA input and output functions to PID control, the following
correlation exist:
mA input mA output
PID control 1 1 2
PID control 2 2 3
P200 mA Output Range
Sets the mA range for the output selected, outputs 1 to 3 (P200 - 01 to – 03).
Entry:
1 = 0 - 20 mA
2 = 4 - 20 mA
f
P201 mA Output Function
Assigns the mA output function for the output selected, outputs 1 to 3 (P201 - 01 to –
03)
Entry:
1 = rate
f
2 = load
3 = speed
4 = PID control output*
* valid for outputs 2 and 3, only if PID system (P400) is enabled
P204 mA Output Average
Sets the averaging period, in seconds, for the rate output for output 1 only.
The instantaneous mA values are averaged for the set period, and then the average
value is output during the next period while a new average is being calculated.
Entry:
0 = off
f
1 – 999 = averaging period
