| PV derivative type PID control and Deviation derivative type PID control |
 Selectable PID control algorithm |
| PID control algorithm is selectable in the FB Series to achieve the most precise control for various applications. PV Derivative PID : suitable for fixed setpoint control (Factory setting) Deviation Derivative PID : suitable for ramp control using ramp-to-setpoint function and cascade control. |

| Selectable sampling time among 50ms, 100ms, and 250ms. |
| Selectable sampling time makes the FB Series suitable for any application
ranging from pressure control requiring fast response to precise control
requiring highest resolution. The selections are 100ms (factory setting)
usually suitable for most of standard applications, 50ms for fast response
applications, and 250ms for precise control requiring high-resolution.
The PID parameters can be set in 1/10 unit which supports fast and accurate
control. Ramp-to-setpoint and output-change-limiter functions are each
settable for UP and DOWN so that a special heater can be controlled precisely. |

| Advanced Heat/Cool PID algorithm with Undershoot Suppression |
| Advanced Heat/Cool PID algorithm achieves stable control by the Undershoot
Suppression (USS) function, and independent P-I-D settings for both Heat
and Cool which are effective for applications with strong cooling gain.
Control Response type selection is settable to avoid overshoot at start-up
and against external disturbance. The FB Series also offers selection of
water cool and air cool PID control algorithm. |
