Dual PID control

The response rate of the PID control can be selected

depending on the characteristics of the control target.

Select high-speed response mode or low-speed response

mode [PIdF, PIdS] from PID method [PIDT] of parameter

group 2.

Temp.

High-

speed

response

mode

[PIdF]

Used to minimize the time (t) required to reach the SV.

Overshoot (S) occurs.

Used in machinery that may require warming up.

(injection molding machine, electric furnace, etc.)

Temp.

Low-

speed

response

[PIdS]

Used to minimize overshoot (S). Time (t) required to

reach SV may be slower.

Used for machinery or environments where overshoot

may cause explosion or fire. (oil temperature control,

metal plating machinery, etc.)

Input correction [ IN-B ]

Used to correct deviation from external devices such as

temperature controllers.

E.g.) If the actual temperature is 80℃ but the display value

is 78℃, set the input correction [IN-B] value to 2 and

it will display 80℃ as the display value.

Manual reset [ REST ]

When using proportional control (P control), the time

of temperature rising time and falling time may differ

depending on factors such as the heat capacity of the

control device or the heater. A certain amount of deviation

occurs even under stable conditions.

This deviation is referred to as offset, and can be

configured/corrected using manual reset [ REST ].

When PV and SV are equal, the reset value is 50.0%. If the

PV is lower than the SV during stable control, set the value

to over 50.0%, and if the PV is higher than the SV, set the

value to under 50.0%

Configuring manual reset [REST] according to control results.

Reset value set at under 50.0%

Offset

Reset value set at over 50.0%

RS485 Communication

Applicable for models that support RS485 communication.

Please refer to '

It is used to transmit PV or SV, and/or set the SV.

communication converter, sold separately), SCM-US48I

(USB to RS485 converter, sold separately), SCM-38I

(RS232C to RS485 converter, sold separately).

Please use twisted pair wire for RS485 communication.

Communication control ordering

1. The communication control ordering of TZ/TZN Series is

exclusive protocol.

2. After 4 sec being supplied the power into master system,

then able to start communicating.

3. Initial communication will be started by master system.

When Command signal comes out from master system

then TZ/TZN Series will respond.
