Page 55 Derivative Action Selection Function
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Derivative action selection
CH Derivative action selection (in the Q compatible mode)
■Setting range
• 0: Measured value derivation
• 1: Deviation derivation
■Enabling the settings
Turn ON and OFF 'Setting change command' (YB) in the setting mode ('Setting/operation mode status' (X1): OFF) to enable
the settings.
■Default value
The default value is Measured value derivation (0).
CH1 Setting variation rate limiter unit time setting
Set the unit time of the setting variation rate limiter. For details on the setting variation rate limiter setting function, refer to the
following:
Page 58 Setting Variation Rate Limiter Setting Function
■Buffer memory address
The following shows the buffer memory address of this area.

CH Setting variation rate limiter unit time setting
CH Setting variation rate limiter unit time setting (in the Q compatible mode)
■Setting range
• 0 (Unit time setting not used)
• 1 to 3600 (s)
When 0 has been set, the temperature control module operation is the same as the operation of when 60 (1 minute) has been
set.
