It is used to select the setting channel of the main frequency. You can set the main frequency in the following 10
channels:
0: Digital setting
(Preset frequency b0-12, UP/DOWN modifiable, not record at power failure)
The initial value of the set frequency is the value of b0-12 (Preset frequency). You can change the set frequency by
pressing
▲
and
▼
on the operation panel (or using the UP/DOWN function of input terminals).
When the Frequency inverter is powered on again after power failure, the set frequency reverts to the value of b0-12.
1: Digital setting
(Preset frequency b0-12, UP/DOWN modifiable, record at power failure)
The initial value of the set frequency is the value of b0-12 (Preset frequency). You can change the set frequency by
pressing keys
▲
and
▼
on the operation panel (or using the UP/DOWN functions of input terminals).
When the frequency inverter is powered on again after power failure, the setting frequency is the value memorized at
the moment of the last power failure.
Note that b0-10 (record digital setting frequency of power failure) determines whether the set frequency is
memorized or cleared when the frequency inverter stops. It is related to stopping rather than power failure.
2: AI1
3: AI2
4: AI3
The frequency is set by analog input. The EM12 control board provides 3 analog input (AI) terminals (AI1,
AI2,AI3).Including:
AI1: 0V~10V voltage inputor 0mA~20 mA current input, determined by jumper AI1 on the control card;
AI2: 0V~10 V voltage input or 0mA~20 mA current input, determined by jumper AI2 on the control card;
AI3: -10V~10 V voltage input
The correspondingrelationship curve between the input voltage of AI1, AI2 and AI3 and the target frequency can be
user-defined.
When AI is used as the frequency setting source, the corresponding value 100% of the voltage/current input
corresponds to the value of b0-13 (Maximum frequency).
5: Pulse setting (HDI)
The frequency is set by HDI (high-speed pulse). The signal specification of pulse setting is 9V~30V (voltage range)
and 0 kHz~100 kHz (frequency range). Pulse can be only input by HDI.
The relation between HDI terminal input pulse frequency and corresponding setting is set by b5-00~ b5-03. The
corresponding relation is the linear relation of these two points. The corresponding value 100% of pulse setting
corresponds to the value of b0-13 (Maximum frequency).
6: Multi-function
In Multi-segment speed mode, combinations of different DI terminal states correspond to different set frequencies.
