2SD 1866 Circuit Configuration
Notes:
1) Peripheral units 1 and 2 cannot be driven simultaneously. To drive them continuously,
set the duty cycle ratio to 20% or less.
2) The status of the compulsion switch can be known from the status command. Refer
to the separate Programmer's Manual for details.
3) Minimum resistance for coils L1 and L2 is 24 W .
4) Absolute maximum ratings for diodes D1 and D2 (Ta = 25°C) are:
Average Rectified Current I
5) Absolute maximum rating for transistors TR1 and TR2 (Ta = 25°C) are:
Collector current I
