AI Analogue Commend Input
• There are three analogue command inputs of
SPR/RTQR (14 pins), CCWTL (16 pins) and
CWTL (18 pins).
• The maximum permissible input voltage is ±0V.
For the input impedance of these inputs, see
the right figure.
• If you make a simplified circuit comprising a vari-
able resistor (VR) and resistor (R), refer to the
right figure.
When the variable range of each input is
- 10V to + 10V, the VR should be a B type
resistor of 2kΩ (min.1/2W). The R should be
200Ω (min.1/2W).
• The A/D converters for these inputs should
have the following resolution.
