AI Analogue Commend Input
AI
・ There are three analogue command
inputs of SPR/RTQR (14 pins), CCWTL
(16 pins) and CWTL (18 pins).
・ The maximum permissible input voltage
is ±10V. For the input impedance of
these inputs, see the right figure.
・ If you make a simplified circuit comprising
a variable 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 2k Ω (min.1/2W). The
R should be 200 Ω (min.1/2W).
・ The A/D converters for these inputs
should have the following resolution.
①
ADC1 (SPR and TRQR) : 16 bits (including one bit for sign)
②
ADC2 (CCWTL and CWTL) : 10 bits (including one bit for sign
