The brake a little dynamic braking circuit


Posted on Mar 28, 2007

Circuit shown in Figure 3-143. The line not only make the braking effect of the motor is in the normal shutdown, and jog through the process and has a good braking effect. Figu

re, SBz the start button, SBz the stop button, SB3 jog button. Normal braking time by the time the decision relay KTi (3-4s, adjustable). When the jog control, if the time interval of less than two jog KTz tuning time (2 ~ 3s, adjustable), the delay does not turn off normally closed contact, then press the SB3 is jogging, pine SB3 that is open to the brake; if the interval is greater than twice jog KT2 tuning time, or jog end, KTz normally closed contacts disconnect timer, relay KAz, KA3 has lost power release, KA3 normally open contact disconnect and contactor KM2 missing, and released end braking.
