Analogue Inputs - JVL MIS17 Series User Manual

2.3
2.3.1 General
The 0-5V Analogue Inputs are used for example when the Controller is operated as a
stand-alone unit. In this kind of application it can be an advantage to use a potentiometer,
joystick or other device for adjusting speed, position, acceleration, etc.
In these modes of operation, the motor is controlled to produce a velocity or position,
etc., which is determined by, and proportional to, the voltage applied to the Analogue
Input.
The Analogue Inputs share a common internal supply with the GND and P- terminal and
are not optically isolated from all other inputs and outputs. The Analogue Inputs are pro-
tected against voltage overload up to 30V peak and have a built-in filter which removes
input signal noise. See
Always use shielded cable to connect the source used to control an Analogue Input since
the motor, etc., can easily interfere with the analogue signal and cause instability.
The Controller is equipped with 8 analogue-to-digital converters (ADC) which convert
the detected analogue signal level. The ADCs have a resolution of 12bit.
In order to use the Analogue Inputs as 0-20 mA inputs, a 250 , 1% resistor must be
connected between IO 1-8 and GND.
