b) Enable by High

Inhibit/CW/CCW functions will be de-activated by connecting their inputs to a high level signal. If no signal is applied to these inputs the amplifier will be disabled upon power on.

For this logic insert 3.6Kohm ( +10%)resistors for R18 (Inhibit), R19a (CW), R20a (CCW). The power of these resistors is calculated according to:

Pmin=V2/1500 (Watt)
