(1) Description of peripheral I/O functions
(a) Inverter timer
Inverter timers are used to output PWM waveforms.
In this application circuit example, the settings are as shown below.
• 20 kHz symmetrical triangular waveform mode
• Dead time: 6
µ
s
• Inverter timer output: Low active
• When ESO0, TOQ0OFF, or INTP000 pin input is at high level, PWM output is stopped.
(b) Motor control timer
Motor control timers are used to issue interrupts at a 50
µ
s interval.
(c) 10 ms timer
10 ms timers are used to issue interrupts at a 10 ms interval.
(d) Speed measuring timer
Used for measuring the revolution speed of the motor.
(e) Current value input
ANI00, ANI0 (V850E/MA3 only): U-phase current value (−5 to +5 A)
ANI10, ANI1 (V850E/MA3 only): V-phase current value (−5 to +5 A)
(f) Speed specification volume value input
ANI01 or ANI4 (V850E/MA3 only) is used to input a value from 0 to 1,023.
