4.12 Manual turning with the adjustment facility
When mounting or dismounting a PSx3xx, it may be necessary to manually turn the
output shaft to a certain position. For this purpose, the actuators are equipped with a
manual adjustment facility:
First, the corresponding cover in the cover must be removed.
Then use a NW3 (PSx31x, PSx33x, or NW4 (PSx30x, PSx32x) hexagon key to
disengage the brake by pressing it down and turn it simultaneously.
An electrical release of the brake via bus is not possible on its own (without travel
job).
The drive must not be turned into another position with an
electric screwdriver
Important! To prevent ingress of dirt and dust, the protective cap
must be reattached after setting the address.
A "forced" turning of the drive without disengaging the brake
leads to the destruction of the brake and thus of the drive!
4.13 Devices with optional snap brake
The device models PSx30x-14, PSx31x-14, PSx32x and PSx33x can be supplied
with an optional snap brake. This brake prevents the output shaft from turning when
the power supply to the motor is removed, or, if the motor holding torque is too low, to
a maximum of the level of the nominal torque. A small degree of rotation always
occurs at the output, i.e. the brake cannot be used to hold the drive at a defined
position (for this purpose the holding torque may have to be increased with the help of
SDO #202B and SDO #2042).
To release the brake when a run command is transmitted, these devices first wait for
a short time and then run a few increments against the actual direction of movement.
The brake is closing at the end of every run (by default 1 sec after the end of the run,
SDO #2045). The advantage of this feature is, that in case of many subsequent runs
the brake has not to be released anew each time.
