Designing a Power ON Sequence
Note the following points when designing the power ON sequence.
D
Design the power ON sequence so that power is turned OFF when a servo alarm signal is
output. (See the circuit figure above.)
D
Hold the power ON button for at least two seconds. The Servopack will output a servo alarm
signal for two seconds or less when power is turned ON. This is required in order to initialize
the Servopack.
2.0 s max.
