Which servo is suitable - digital or analogue?
One major difference is that a digital servo can move to its position faster and hold the
position more accurately. An analogue servo uses an ohmic potentiometer that loses
its repetition accuracy with temperature chages (tolerance).
Both types of servo can be connected to the ReadyServoTurn.
In the case of an effect, the advantage of the digital servo might make a difference. For
a turnout or other movements with a mechanical positioning spring and strain relief,
the tolerance is unimportant. Here a large travel distance should be chosen and servos
with metal gears should be used. In the FichtelBahn-Shop you will find a reliable and
inexpensive solution with the article no. 410100
04.3.1 Servo protection mechanisms
The ReadyServoTurn is designed for operational safety
with monitoring functions.
Each servo output has overcurrent and short-circuit
detection, which switches off the affected servo output
in the event of a fault. The remaining servo outputs can
still be used.
The error status (shut-off of a servo output) is signalled
by a static red error LED on the module.
If a new servo control command is issued for the defective
output, the control programme receives a message via the ac-
cessory feedback that the servo output could not be switched
and therefore the route is not locked.
The shut-off and error message can only be reset with a
power reset of the ReadyServoTurn.
Please notice:
The overcurrent and short-circuit detection is designed for a continuous load of
500mA / peak = 1A for each servo port.
