10.2.3.2. Single Power Supply Topology (VP+ < 40VDC)
A single power supply can be used to power both the main and control. For the CAN version
power rating of minimum 12VDC to 40VDC, or minimum 14VDC to 40VDC for the EtherCAT
version.
When regeneration or braking occurs, the DC bus may increase and may exceed the VL limit of
over 40VDC, possibly causing the VL to fail. Under these conditions, you must install the Dual
Power Supply described above in section 10.2.3.1.
10.2.3.2.1 Recommended Option
This option describes an Ordinary power supply for Servo drives with sufficient internal
capacitance and shunt regulator to handle power flow in both directions to-and-from the motor.
In this configuration the Gold Twitter max operating voltage depends on the model, and is 55VDC,
75VDC, or 95VDC. However the DC bus must be limited to VP+ <40VDC to prevent failure of the VL
supply.
The following figure describes this connection of main power and control
Figure 18: Recommended Single Power Supply (VP+<40V) Connection Diagram with VL+ Connected Internally
Note:
This option is available for power supply up to 40VDC.
For applications where the recommended single power supply is used, the following conditions
must apply:
•
The “Shunt On” trip voltage in the power supply must be <40VDC
•
If there is no shunt in the Power Supply the Over Voltage must be programmed using the
drive software command
XP[1] =38 (over-voltage set to 38V)
•
Minimum capacitance of the Power supply: C
Power_Supply
> Drive’s Rated Current *20uF
•
The VL- to PR is connected on the Integration Board (no external wiring)
•
The VL- to PR connection must be as thick as possible, actually a Ground Plane is most
preferable
