When specifically requested by the customer, other types of encoders and/or servo sensors can be fitted. Please check with
VASCAT for each specific case.
Parking brake
3.8.2
ID series motors can be fitted, as an option, with an electromagnetic parking brake to immobilise the motor load safely and in a
way that is 100% external to the operation of the motor itself.
On certain occasions, this is necessary for safety reasons, e.g. when it is necessary to block the movement of the machine to
work on the interior safely or when there is a fault in the converter power supply or other mechanical devices of the installation.
PRECAUTION
The use of the parking brake as a dynamic working brake, e.g. to slow down a load, is not allowed, since it speeds up the
premature wear and tear of the lining.
In general, the brakes are powered at 24 VDC (please check the technical datasheet of each motor), working via the activation of
coils on springs. This type of brake works according to the lack of voltage operating principle, i.e. when there is no voltage
applied, the brake blocks the rotation and when voltage is applied, it is unblocked.
PRECAUTION
If the appropriate voltage is not applied to the brake, it will not work correctly. In the case of insufficient voltage, it will overheat due
to friction, causing rapid wear and tear of the lining. If the voltage is too high, the windings may be damaged by surge currents.
PRECAUTION
The brake power circuit must be completely independent.
Make sure that the brake is not activated before the motor rotates and that it remains connected to voltage when the motor is
rotating. If, for any reason, the power supply to the brake continues when the motor is stopped, the brake will not work and, as the
shaft would be free, undesired movements may occur.
The correct use of the brake is the user's responsibility and that of the manufacturer of the electrical control cabinet.
The specifications of the standard brake for each type of motor are specified on the corresponding technical data sheet, which
can be consulted on VASCAT's website:
NB
The friction surfaces must always be kept free from oil and grease, since minimum quantities of such substances can largely
reduce the brake torque.
