How to Operate
Set up relevant parameters using the table below.
Parameter Address Default value Range

Filter range 10F9H 1.0 0.1~10.0
Hot Runner Control
Function
The hot runner control includes 3 steps:
1. Heating up by constant output volume
2. Timed PID control (Soak)
3. Slope heating to the target temperature (SV)
How to Operate
1. Enable the hot runner control function: Write 1234H into the address 47F1H and then 0060H into address 4824H.
Bits in 4824H Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0

Notes:
The flag to enable hot runner control is at bit6 of 4824H (and bit5 as to be enabled at the same time). Write 0060H to set both bits on.
If there is already a set value in 4824H and you would like to modify it, reset it to 0 before you set up a new value.
2. Set up relevant parameters using the table below.

Temp. bound（unit: 0.1°） 1960H 1961H 1962H 1963H 1964H 1965H
Constant output volume（unit: 0.1%） 1968H 1969H 196AH 196BH 196CH 196DH
Timed time（unit: min.） 19B0H 19B1H 19B2H 19B3H 19B4H 19B5H
Target temperature（uint: 0.1°） 1008H 1009H 100AH 100BH 100CH 100DH
Slop（unit: 0.1°） 1970H 1971H 1972H 1973H 1974H 1975H
Example
Assume the temperature bound is 100.0, constant output volume is 35.0, timed time is 15, target temperature is 200.0 and slope is 20.0, thus
1. The heater outputs by the 35% constant volume and waits for the temperature to rise to 100 degrees,
2. When the temperature hits 100 degrees, switch to the PID soak mode and retain the temperature constantly for 15 minutes.
3. When the time is up, switch to the slope control mode, executing the condition of a 20 degree temperature rise every minute.
4. When the heating achieves 200 degrees, the hot runner control is completed.
RS-485 Communication
1. DTE supports baud rates 2,400/4,800/9,600/19,200/38,400/57,600/115,200 bps and does not support communication format 7, N, 1/8, E,
2/8, O, 2. Communication protocol = Modbus ASCII or RTU.
2. Function codes: H03 = read maximum 8 words in the register; H06 = write 1 word into the register.
3. Address and contents: Every parameter has 2 communication addresses. One is numbered by the function of the parameter, and the other
is by the order of channel (as shown in the table below).
