When A04 = 0, the operation speed is given by the code of multi-step port 0 – 2;
When A04 = 1, the operation speed is given by the input voltage (0 - +10V) from the
analog voltage input port AI1; when the input voltage is not within 0 - +10V, H02 (AI1
analog offset) and H03 (AI1 analog gain) shall be configured. See 6.2.8 H (Analog Input)
Parameters for more information.
When A04 = 3, the operation speed is given by the input current (4 – 20mA) from the
analog current input port AI3. When the input current is not within 4 – 20mA, H10 (AI3
analog offset) and H11 (AI3 analog gain) shall be configured. See 6.2.8 H (Analog Input)
Parameters for more information.
2. Port Setting
a) Analog voltage input port
Analog voltage signals may only be input through the analog voltage input port AI1.
b) Analog current input port
Analog current signals may only be input through the analog current input port AI3.
c) Multi-step input port
By means of the function codes F01 – F12, multi-step input ports may be selected from
the digital input ports DI1 - DI12. Multi-step port 0, 1 and 2 may only be given one port
