Hello Everyone
i have a doubt: i have yaskawa servo pack( driver) SGDF-A2CS , my
question is can i connect PWM o/p generated from PIC to driver speed control(
analog voltage ) input directly....is it safe for the driver?.....pwm frequency
is 15khz .. is this frequency ok?...
Please reply...
Thanx

A PWM
output (50-50 or locked anti-phase?) does not give you the analog voltage
required to drive the servo amplifier. If it is an analog voltage you are after,
you would need additional interface logic (including a DAC) to take your PWM and
change it to an analog voltage.
