Panasonic A6 Servo Motor and Driver Instruction — Built-in Holding Brake

Abstract

In the applications where the motor drives the vertical axis, this brake would be used to hold and prevent the work (moving load) from falling by gravity while the power to the servo is shut off.

Caution →

Use this built-in brake for "Holding" purpose only, that is to hold the stalling status. Never use this for "Brake" purpose to stop the load in motion.

Connecting Example

The following shows the example when the brake is controlled by using the brake release output signal (BRK-OFF) of the driver.

Note → 1. The Brake coil has no polarity.

Caution → 2. Power supply for the brake to be provided by customer. Do not co-use the power supply for the brake and for the control signals (VDC).

3. Install a surge absorber as the above Fig. shows to suppress surge voltage generated by ON/OFF action of the relay (RY). When you use a diode, note that the time from the brake release to brake engagement is slower than that of the case of using a surge absorber.
4. For a surge absorber, refer to P.7-146, "Recommended Components" of supplement.
5. Recommended components are specified to measure the brake releasing time.
Reactance of the cable varies depending on the cable length, and it might generate surge voltage.
Select a surge absorber so that relay coil voltage (max. rating:30V, 50mA) and terminal voltage may not exceed the rating.

Output Timing of BRK-OFF Signal

For the brake release timing at power-on, or braking timing at Seervo-OFF/Servo-Alarm while the motor is in motion, refer to P.2-42, "Timing Chart".
With the parameter, Pr4.38 (Setup of mechanical brake action while the motor is in motion), you can set up a time between when the motor to a free-run from energized status and when BRK-OFF signal turns off (brake will be engaged), when the Servo-OFF or alarm occurs while the motor is in motion.

Note →

The lining sound of the brake (chattering and etc.) might be generated while running the motor with built-in brake, however this does not affect any functionality.
Magnetic flux might be generated through the motor shaft while the brake coil is energized (brake is open). Pay an extra attention when magnetic sensors are used nearby the motor.

Excitation voltage is DC24 V ±100% (MSMF 50 W to 750 W DC24 V±1.2).
Releasing time values represent the ones with DC-cutoff using a varistor.
Above values (except static friction torque, releasing voltage and excitation current) represent typical values.
Backlash of the built-in holding brake is kept ±1^° or smaller at ex-factory point.
Service life of the number of acceleration/deceleration with the above permissible angular acceleration is more than 10 million times. (Life end is defined as when the brake backlash drastically changes.)

Q & A About Robotic Arms and Injection Automation

For vision control system for IML containers, what's the advantages and disadvantages of the open type of vision control system?

Vision control is now a very important in IML system especially the IML solutions for dairy products packages like yogurt cups, butter cups etc. For most European IML solutions providers like BRINK that they'll choose an open type of Vision control system which will check if the containers are well labeled or not immediately after the containers picked out from the mold and have them re-stacked after the vision control. This kind of solution will help to increase the efficiency of the IML System and pick out the defect parts quickly.

But, for some minor defect like dirt it would be impossible to be checked out because the precision of the cameras would be influenced by the changing light of the environment. To solve this problem the updated solution would be to have the IML containers checked in a closed light box which will creat a stable environment to the camera to minimize the misjudgement of the good and non good parts. -- SWITEK Yogurt Cups Vision Control Solution
