Hi.
Could you help me to understand the robot system. In manual mode I press the start button and start to move robot by joystick. In this case, the brakes are unlocked on all axles or the motors overcome the brake force? Maybe another scheme of work?
Thanks.

Break release possible only when a "Motor on" status.
simply, hold operation replace between break and Motor torque (reduction gear)
-
When the servo power is applied to the motors, 24VDC is supplied to the brakes to disengage them and allow motion. The motors do not overcome the brakes - imagine driving a car with the brakes fully applied.
To send you on your way to learning about the brakes, I searched "Explanation of servo motor brakes" and got this vidoe: "

Depending on the system, you will hear the brakes "click" off when you operate the dead mans switch or start to move the joystick, the system will apply power to the servo motors before releasing the brakes.

Ok, when i hear that "click", the breaks are off and the system applies power to the servo motors and thus the system keeps the robot from falling.
And in order for it to work, there must be a current between the windings.
I checked the voltage between the windings, but the tester showed nothing.
And how could i check the voltage on each winding?
Maybe I'm asking stupid questions, but I just do not understand how this system works and I'm trying to figure it out.
Thanks. -
Often, the brakes do not release simply with deadman activation - they "click" when you try to move an axis. They also "click" (or a louder "clack") when you release the deadman (or if the system faults).
