Designing a Power ON Sequence
Note the following points when designing the power ON sequence.
• Design the power ON sequence so that main power is turned OFF when a servo alarm signal is output.
(See the circuit figure above.)
• Hold the power ON button for at least two seconds just after the control power is turned ON. 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.
• Select the power supply specifications for the parts in accordance with the input power supply.
Power Supply Harmonic Waves
If a countermeasure against power supply harmonic waves is needed for other requirements, insert the AC
reactor to AC power supply input of the SERVOPACK or insert the DC reactor to the internal DC main
circuit.
Refer to
5.6.5 AC/DC Reactor for Harmonic Suppression.
(3) 800 W, Single-phase 200V
Note: L3 terminal is not used for the single-phase 200 V, 800 W SERVOPACKs. Do not connect.
