In the Amplifier SD3100C412 (1 kW), single-phase can be used for primary circuit power source.
To use single-phase 200 to 240 VAC, connect it to the primary circuit power connectors L1 and L3.
Notice
Use SELV
(Safety Extra Low Voltage/Non-Hazardous Voltage)
power supply with reinforced isolation from hazardous voltage.
As a countermeasure against amplifier failure, install overcurrent protection or use power output capacity of no
higher than 100 W.
The current consumption values in the table assume that no I/O signals except the Servo-On signal are connected.
Current consumption by all I/O signals in use must be added up.
If multiple amplifiers are to share control power, select power source that will support the total inrush current of all
connecting amplifiers.
Regenerative resistor values do not guarantee optimal performance. If the generated heat temperature becomes too
high, increase the resistance value or select a resistor whose allowable power is larger enough. Whether or not a
regenerative resistor installation is necessary can be checked on the Setup Panel or "Servo Studio".
3 Preparation
5 Setting Parameters
SD3 series amplifiers are equipped with a software-based dynamic braking function to stop the equipment.
This dynamic braking function does not necessarily work in case of disconnection from control power such as
amplifier failure and power outage.
If you are to make your own dynamic brake circuit, perform thorough testing before actual use.
3 Preparation
The minimum time interval varies depending on input format.
4 Connections
When mounting amplifiers to an enclosure such as a protection case, install a cooling devise, or secure required
clearance around it so that ambient temperature will not rise above the specification temperature.
3 Preparation
For 2 kW amplifier (SD3100C412), refer to the following temperature derating curve.
