1. Use SELV power.
※
SELV power: Safety Extra Low Voltage
Reinforced insulation is needed for safety extra low voltage, non-dangerous voltage and dangerous voltage
As the overcurrent protection for drive failure, please select the power supply of 100W or less.
Current consumption is the value of I/O signal without the connection of servo ON.
Increase the current consumption for the I/O signal occupied points in the actual usage.
Note 2) The installation of regenerative resistor can be confirmed by the set panel.
1. Select
in the Status Display mode.
2. Show the regenerative state
3. When the device reaches the actual working speed from the low speed (about 20% of the highest speed), confirm the set
panel display is changed to
4. When the panel changes to
, install the regenerative resistor according to [table 1.4.1 Model selection of
peripheral braking resistor].
5. The regenerative resistor value in table 2-2-2 cannot guarantee the performance. If the heating temperature is too high,
please choose the large and high power resistor.
Note 3) The brake is the dynamic brake function controlled by the software.
The brake function becomes invalid when the drive failure occurs or the power supply disconnect.
Note 4) Pulse command input is shown below.

The rise and fall time of command pulse input signal should be 0.1μs or less.
※
The pulse is counted from Low to High.
※
Pulse command input filter selection(No.33.0) should be set according to the input frequency.
