Trigger pulse duration can be disturbed by noise signals
generated by the triac itself, which interfere within Pins 14
and 16, precisely those which determine it. While easily
visible, this effect is harmless.
The triac must be protected from high AC line dV/dt
during external disturbances by 100 nF x 100
network.
Shunt resistor must be as non–inductive as possible. It can
be made locally by using constantan alloy wire.
When the load is a DC fed universal motor through a
rectifier bridge, the triac must be protected from
commutating dV/dt by a 1.0 to 2.0 mH coil in series with
MT2.
Synchronization functions are performed by resistors
sensing AC line and triac conduction. 820 k values are
normal but could be reduced down to 330 k in order to detect
the “zeros” with accuracy and to reduce the residual DC line
component below 20 mA.
Current Limitation
The current limiter starts to discharge Pin 7 capacitor
(reference speed) as the motor current reaches the designed
threshold level. The loop gain is determined by the resistor
connecting Pin 3 to the series shunt. Experience has shown
that its optimal value for a 10 Arms limitation is within
2.0 k
. Pin 3 input has a sensitivity in current which is
limited to reasonable values and should not react to spikes.
If not used, Pin 3 must be connected to a maximum
positive voltage of 5.0 V rather than be left open.
Loop Stability
The Pin 16 network is predominant and must be adjusted
experimentally during module development. The values
indicated in Figure 4 are typical for washing machine
applications but accept large modifications from one model
to another. R16 (the sole restriction) should not go below
33 k, otherwise slew rate limitation will cause large transient
errors for load steps.
