Pin No.
Symbol
Pin Description
Equivalent Circuit
19
FC
Frequency characteristics correction for the
current control circuit.
Insert a capacitor (about 0.01 to 0.1
μF)
between this pin and ground.
The output duty is determined by comparing
the voltage on this pin to the PWM oscillator
waveform.
21
PD
Phase comparator output.
The phase error is converted to a pulse duty
and output from this pin.
22
EI
Error amplifier input.
23
EO
Error amplifier output.
24
TOC
Torque command voltage input.
This pin is normally connected to the EO pin.
When the TOC voltage falls, the lower output
transistor on duty is increased.
