Stober SD6 - Function

Holding brake

Manual SD6
Brake controlled internally (Automatic) by the drive controller or externally by a
control unit.
CAUTION!
Unexpected machine response!
During external control the brake does not automatically engage after enable
is turned off and when faults occur.
 Make certain there is a suitable process in the control unit. Take suitable
measures to ensure safety.
Interface to the motion core with F92[0] = 1:External(fault).
F92[1] is written to CiA 402 from A515 bit 14.

0: internal (automatic) The drive controller assumes the following
functions:
• The brake is automatically released at the
correct time for movement commands.
• Brake release time and brake set time are
monitored and the brake status signals
F08 and F09 are operated.
• When the brake is set, no torque is
generated by motor control (power is not
supplied to the motor).
• With control types with vector control B20,
the holding torque/force is determined and
restored when the brake is released
(F103).
• Before the brake is released a test
determines whether sufficient flux has built
up to switch on enable.
1: external (plc) The drive controller assumes the following
function:
• The brake status signals F08 and F09 are
operated.
A controller must assume the following
functions:
• Application and release of the brake for
motion commands in good time.
• Monitoring of the brake release time and
brake set time
• Determination and restoration of the
holding torque/force (A593, F102) when
releasing the brake.
• Check of the magnetization for
asynchronous motors before releasing the
brake.
Information
Note that the time between two release processes of the brake
must be at least 1 second. If this requirement is not complied with,
the second release process will be delayed.
