Power Supply Sizing
The current loading on the power supply for a group of MotionLinx-Ai Modules depends upon the Motor Type selected. Each of the motor types available has an associated rated current that the motor will draw at rated torque and maximum speed. Each Motor Type also has an associated allowed current draw that is available for a period of time upon the initial starting of the motor. Theses current values and starting times are shown in the following chart:
|
ECO |
ECO + |
BOOST |
BOOST 8 |
| Power supply load at rated torque at maximum speed |
2.5 A |
4.1 A |
3.5 A |
3.5 A |
| Power supply load during motor starting period |
3.0 A |
4.1 A |
5.0 A |
8.0 A |
| Duration of motor starting period |
5.0 sec |
N/A |
1.5 sec |
3.0 sec |
*Please note that the current values shown are per Motor Port, so if both Motor Ports are being used on a given MotionLinx-Ai, the current load seen by the power supply for that module will be 2X the value shown.
*The current values are at rated speed and at rated torque. The current will be less if rated torque is not required by the motor.
*See MotionLinx-Ai SDOs Configuration Topic for details on selecting Motor Type
!Pulseroller assumes the user is aware of MDR power requirements for the application and that the user and/or installer have properly sized 24VDC power supplies and wiring based upon all applicable codes and standards. Pulseroller also assumes installation will follow proper equipment grounding practices. “DC common or -”on all power supplies should always be connected to ground. Improper power supply sizing and/or improper grounding practices may produce unexpected results
