C - 12
CP-67 DERIVATIVE
In systems with a very large inertia, use Derivative (CP-67) to reduce the overshoot from the
integral term. Decrease the value of Derivative (CP-67) until the overshoot is acceptable. The
system may operate erratically or become unstable if the value of Derivative (CP-67) is too
small.
CP-70 DEVICE ADDRESS
Device Address (CP-70) is the physical address of the ML–Trim, which can be set from 1 to 32.
Each individual ML–Trim on a multidrop RS485 communications link needs a unique Device
Address. The address “00” will be globally accepted by all of the ML–Trims on a
communications link, however, they will not send a response message back to the host computer
when this global address is used.
CP-71 BAUD RATE
There are six different baud rates (data rates) for the ML–Trim. Enter the number for the
required function in Baud Rate (CP-71), as listed below.
1 = 300 Baud
2 = 600 Baud
3 = 1200 Baud
4 = 2400 Baud
5 = 4800 Baud
6 = 9600 Baud
CP-72 CHARACTER FORMAT
The ML–Trim uses three different character formats. Enter the number for the required format in
Character Format (CP-72), as listed below.
1 = 8 Data Bits, No Parity, One Stop Bit
2 = 7 Data Bits, Even Parity, One Stop Bit
3 = 8 Data Bits, No Parity, Two Stop Bit
