Mitsubishi MELSEC System Q User Manual

3.6.2 Temperature Control Modules with PID Algorithm
These modules enable PID algorithm temperature control without placing any load on the PLC
CPU for the temperature control tasks.
Special features
쎲 Four temperature input channels and four PID control circuits per
module
쎲 Temperature acquisition either with Pt100 resistance thermometers
(Q64TCRT and Q64TCRTBW) or thermocouples (Q64TCTT and
Q64TCTTBW)
쎲 The modules 64TCRTBW and Q64TCTTBW can detect the disconnec-
tion of a heater
쎲 Auto-tuning function for the four PID control circuits
쎲 Transistor output with pulse train to drive the actuator in the control
circuit
3.6.3 High-Speed Counter Modules
The modules QD62E, QD62, and QD62D detect signals at a frequency too high for normal
input modules.
Special features
쎲 Maximum counting frequency up to 500 kHz
쎲 Input for incremental shaft encoder with automatic forward and back-
ward detection
쎲 Preset and selection of counter function via external digital inputs
쎲 32-bit counting range(-2 147 483 648 to +2 147 483 647)
쎲 Can be used as up, down or ring counter
쎲
All modules offer two counter inputs
쎲
Two digital outputs which are set according to the counter value per
counter input
All modules are connected via a 40-pin plug.
