Duty Setting Section 5-3
5-3 Duty Setting
The duty setting function is used to the set rate of change from 0% to 100% of
the output value in relation to the input value (analog input signal, key input
setting, or external variable resistor setting).
There are two duty settings, internal and external. The internal duty setting is
held in the internal memory area and the external duty setting is set by using
an external variable resistor. The duty that is used is the product of the inter-
nal and external duty settings.
Duty value (%) = Internal duty setting (%)

External duty setting (%)
Internal Duty Setting • The internal duty setting is made using either key inputs or communica-
tions (Constant-current Models only).
• The duty setting is held in the internal memory area even when the power
is interrupted.
• The duty is set in the adjustment level (DTY).
External Duty Setting • The external duty setting is made using an external variable resistor.
• To use the external duty setting function, set the External Duty Input
Enable/Disable parameter [P01] to 1 (enable) in the initial setting level.
