Action
Fit the motor by gently lowering it straight down.
Tighten the four attachment screws and washers.
In order to release the brakes, connect the 24
VDC power supply to the motor.
Fit the measuring tool to the rear of the motor.
Rotate the motor shaft several turns, using the
measuring tool.
There must always be some backlash, meaning
that the shaft should go easy to rotate!
Place the tip of a dial indicator against the scribed
mark on the measuring tool.
Set the gear play to 0.02 mm, which corresponds
to a reading on the dial indicator of 0.13 mm.
Pull gently in one direction. Note the reading.
(The gear must not turn.)
Then gently knock on the tool in the other direc-
tion and note the reading. The difference in
reading = gear play. The gear play should be 0.02
mm which corresponds to a reading on the dial
indicator of 0.13 mm.
Tighten the motor attachment screws.
Refit the connection box with the three attach-
ment screws and plain washers.
Make sure the gasket is fitted properly!
