• PID command by Operator (J02 = 0 (Factory default state))
With the /
dancer control) can be set to a value obtained by conversion to an easy-to-identify display such as
physical quantity by PID Control Maximum Scale (J106) and PID Control Minimum Scale (J107).
• PID command 1 by analog input (J02 = 1)
The PID command value can be set arbitrarily by multiplying the gain with the PID command value
based on analog input (the voltage value input to the terminal [AI1] and terminal [AI2] (AIV function),
and the current value input to the terminal [AI2] (AII function)), and then adding the bias. Polarity
selection, filtering and offset adjustment are also possible. In addition to setting of J02, PID com-
mand 1 must be selected for each analog setting (parameters E61, E62 and E63) as well.
• PID command by UP/DOWN control (J02 = 3)
If UP/DOWN control is selected as the PID control command, and either "UP" or "DWN" is turned
ON, the command value of PID control fluctuates in the range of maximum scale to minimum scale
accordingly.
To make the setting of the PID command by UP/DOWN control, it is necessary to allocate "17: UP
(UP/DWN function accelerated)" or "18: DWN (UP/DWN function decelerated)" to the input terminals
[DI1] to [DI7].

In the inverter, the PID control values set by the UP/DOWN control are maintained internally, and
when the operation is resumed (including when the power is turned ON), the control is started from the
previous PID command value.
When analog input is applied to the PID command value, the following gains, biases, filters and offsets
are applicable.
M1 Series Standard Type User's Manual (I669)
PID command 1 (Analog input: Terminals [AI1], [AI2] (AII function), [AI2] (AIV function))
Setting based on the voltage value (0 to ±10 VDC, PID 100% command/±10 VDC) input to
the terminal [AI1].
Setting based on the current value (4 to 20 mA DC, PID 100% command/20 mA DC) input to
the terminal [AI2] (AII function).
Setting based on the voltage value (0 to 10 VDC, PID 100% command/10 VDC) input to the
terminal [AI2] (AIV function).
PID command by the UP/DOWN commands
With the UP command "UP" and the DOWN command "DOWN," the PID control commands
0% to 100% can be set to a value obtained by conversion to a physical quantity by PID Con-
trol Minimum Scale (J107) and PID Control Maximum Scale (J106).
