Drive unit DAE-01 CL

3. General information
The drive unit is based on a powerful BLDC motor (brushless DC motor),
which is controlled by a powerful Fujitsu 16 bit microcontroller (auto-
motive standard). This enables functions that underline the outstanding
position of this drive unit:
• Quartz precision speed control.
• Individual adjustability of all speeds with extrem high precision.
• Flexible, variable drive dynamics to accommodate different
belt/platter pairings.
• Pitching (almost) without limits.
• The Motion Care function with individual settings automatically
maintains drive belt and bearings.
• Recording operating time for drive belt and pickup.
The following parameters can be stored:

Operating statuses
The drive unit is always in one of the following operating statuses:
• ON:
The drive unit is ready for use.
• OFF:
The drive unit is in standby mode and is awaiting its next use.
• Motion Care function:
The drive unit „wakes up“ after a waiting period and turns the turn-
table only for about 20 s to maintain the drive belt and bearings at a
lowered speed.

3.2.1
The motor runs
When the motor runs, the corresponding speed of the platter is displayed.
If a speed deviating from the standard value has been selected („Pitch“),
the display shows the actual speed.
If the motor accelerates or brakes,
the target speed display flashes to indicate
that the target speed has not yet been achieved.
The characteristics of this dynamic can be configured, which means that
the duration of this process varies depending on the setting (

The motor is stopped

3.2.3
The motor is stopped and there are alerts
The drive unit records the operating time of the components „drive belt“
and „pickup“. A maximum operating time can be set for each of these
components. If one or more of the components reaches the maximum
operating time, a alert message appears on the display.
If the adjustable limits for the max. operating time of the drive belt or
one or more pickups are reached, the corresponding alerts are displayed,
alternating with the display for the currently active pickup, indicating that
the selected maximum operating time of a component has been achieved.

NOTE:
These warnings are only notes on possibly worn com-
ponents.
They do not affect the functionality of the drive unit in
any way however!
