Compact design
Simple operation
Simple wiring
Improve environmental resistance
Yaskawa SGDA-01BS servo package with superior features and performance. Its compact design allows a
volume ratio of about 1/4 that of conventional servo amplifier models. SGDA-01BS has automatic tuning function,
point-and-click operation, various monitoring functions and PC monitoring functions. It is also compatible with incremental
encoder or absolute encoder feedback. The servo amplifier circuit board is coated with varnish to improve environmental resistance.
Yaskawa SGDA-01BS in the servo amplifier, the pre-magnetic amplifier synthesizes three input signals and one
feedback signal into the deviation signal, and amplifies it into the voltage signal U22-21 output. At the same
time, the output voltage is converted into a trigger pulse by trigger 1(or 2) to control the thyristor turn-on of the
main circuit 1(or 2) of the thyristor, so that the AC 220V power is added to the winding of the two-phase servo
motor to drive the two-phase servo motor to rotate. When △1>0, U22-21>0, flip-flop 2 and main loop 2 work, and
the two-phase servo motor turns positive; When △1<0, flip-flop 1 and main loop 1 work, and the two-phase servo
motor reverses; The circuit composition and parameters of the two sets of triggers and the main circuit of the two
sets of thyristors are exactly the same, so when the input signal and the position feedback current If are in equilibrium, the
output of the pre-amplifier U22-21≈0, there is no trigger pulse output of the two triggers, the thyristors in the main
circuit 1 and 2 are blocked, the power supply of the two-phase servo motor is disconnected, and the motor stops rotating.
