functions 12 to 15) in Group C1. The multiple segments speed indicates percentages of the value of b0-13
(Maximum frequency).
If a DI terminal is used for the Multi-function function, you need to perform relatedsetting in group b3.For details,
refer to the descriptions of Group b3.
7: Simple PLC (built-in)
When the simple programmable logic controller (PLC) mode is used as the frequency source, the running frequency
of the frequency inverter can be switched over among the 16 frequency points. You can set the holding time and
acceleration/deceleration time of the 16 frequency points. For details, refer to the descriptions of Group C2.
8: PID
The output of PID control is used for the source of running frequency. PID control is generally used on-site
closed-loop control, such as constant pressure closed-loop control and constant tension closed-loop control.
When applying PID as the frequency source, and the keypad is at the zero class menu, then to press UP/DOWN
button, the inverter will automatically enter into the PID digital setting(C0-01) parameter to change the setting.
When the power is off, it will save the setting value.
9: Communication setting
The frequency is set by means of communication.

Communication setting
When used as an independent frequency input channel (frequency source switched over from X to Y), the auxiliary
frequency source Y is used in the same way as the main frequency source X (refer to b0-03).
When the auxiliary frequency source is used for operation (frequency source is "X and Y operation"), pay attention to
the following aspects:
1.
If the auxiliary frequency source Y is digital setting, the digital setting frequency (b0-12) does not take effect.
You can directly adjust the set main frequency by pressing keys and
on the operation panel (or using the
UP/DOWN function of input terminals).
2.
If the auxiliary frequency source is analog input (AI1, AI2 and AI3) or pulse setting, 100% of the input
corresponds to the range of the auxiliary frequency Y (set in b0-05 and b0-06).
3.
If the auxiliary frequency source is pulse setting, it is similar to analog input.
Note:
The main frequency source X and auxiliary frequency source Y must not use the same channel. That is, b0-03
and b0-04 cannot be set to the same value in case of confusion.
