There are two channels Al1 and Al2 and three modes to be selected for analog quantity
input:
[Channel 1] 0: 0-10V 1: 0-5V
[Channel 2] 2: 0-20mA/0-10V 3: 4-20mA/2-10V
[Overlying of channel 1 and channel 2] 4: Overlying of 0-10V and 4-20mA/2-10V
[Note] Current or voltage input can be selected by channel 2 through jumper J1
This parameter can be set to satisfy different analog input signals.
When P070=4, output frequency is equal to 1/2 (U/Umax+I/Imax) x50Hz, wherein:
U: analog quantity voltage
I: analog quantity current
Umax: Maximum analog quantity voltage
Imax: Maximum analog quantity current
