1.1 Main Features of the E5AR/ER
1-3
Overview
• Selection of a PID is possible not only by direct specification of the
PID Set No. in a bank, but also by PID set automatic selection
according to the present value and deviation.
● Ample control
modes and control
functions
• Supports typical control modes (standard control, heating/cooling
control, proportional control, cascade control). Note that proportional
control and cascade control are only possible on 2-input types.
• Floating control or closed control can be selected for position
proportional types. Floating control allows position proportional
control without a potentiometer.
• Remote SP
Two-input types can use an external input for the set point.
• SP ramp function
This limits the amount of change of the set point based on the rate of
change (SP ramp value). This function is useful for control applica-
tions such as firing ceramics where sudden changes in temperature
are not desirable.
The E5AR/ER allows an SP ramp rise value and fall value to be set
separately.
■ Outputs
● Multi-output • Multi-output supporting current output and voltage output (pulse) is
available.
● High resolution • Resolution of current output
0 to 20 mA: Approx. 54,000 resolution
4 to 20 mA: Approx. 43,000 resolution
● Control period • The control period can be set as short as 0.2 seconds, allowing
precise time sharing proportional control.
