1 OVERVIEW
This manual describes the specifications, handling, wiring, and programming of the
loop control module Q62HLC (hereinafter abbreviated as Q62HLC) that is used with
the MELSEC-Q series programmable controller CPU.
(1) About Q62HLC
1 - 1
(a) The Q62HLC is intelligent function module for the continuous proportional
control.
The Q62HLC converts analog input from various external sensors
(temperature, humidity, pressure, and flow rate) into a measured value (16-bit
signed binary data), performs PID operations to attain the target set value,
and outputs the calculated manipulated value to external operation devices
with current output.
(b) The Q62HLC has the following five control functions.
• Normal control (Normal control mode)
• Program control (Program control mode)
• Cascade control
• Manual control (Manual control mode 1)
• Manual control (Manual control mode 2)
(c) The Q62HLC automatically sets the proportional band (P), integral time (I),
and derivative time (D) for PID operations using the auto tuning function.
(d) Thermocouples (K, J, T, B, S, E, R, N, PLII, and W5Re/W26Re type) and
sensors compatible with the input ranges of micro voltage, voltage, and
current can be connected to the Q62HLC.
