-4999-4999 0 The minimum reference is the lowest value obtainable by summing all
references
-4999-4999 50 The maximum reference is the highest value obtainable by summing
all references
-100-100% 0 Enter the set point

0-10V 0.07V Enter the voltage that corresponds to the low reference value
0-10V 10V Enter the voltage that corresponds to the low high reference value
0-20mA 4 Enter the current that corresponds to the high reference value
0-20mA 20 Enter the current that corresponds to the high reference value

set in 6-21 Terminal 54 High Voltage/6-23 Terminal 54 High Current
0-10 s 0.01 Enter the filter time comstant
0 Select Normal [0] to set the process control to increase the output
[1] Inverse speed when the process error is positive. Select Inverse [1] to reduce
the output speed.
0-200Hz 0 Enter the motor speed to be attained as a start signal for
commencement of PI control
0-10 0.01 Enter the process controller proportional gain. Quick control is
obtained at high amplification. However if amplification is too great,
the process may become unstable
0.1-999.0 sec. 999.0 sec. Enter the process controller integral time. Obtain quick control through
a short integral time, though if the integral time is too short, the
process becomes unstable. An excessively long integral time disables
the integral action.
