HIPERFACE

3.2.2
The SinCos motor feedback system with the standardized
Hi

,
HIPERFACE for short, is often used in digital drive technology because of its high and absolute
position resolution. In this case, search for reference is not required. The features of this system
are as follows:
1024 sine/cosine cycles per revolution;
Absolute positioning with a resolution of 32768 increments per revolution
4096 revolutions can be measured in multiturn mode (SRM)
Unlike the resolver, the SinCos motor feedback system with HIPERFACE

interface contains
electronic components. The system still distinguishes itself by high thermostability and high
immunity to noise.
HIPERFACE DSL
®
3.2.3
The SinCos motor feedback system HIPERFACE DSL
®
is a digital extension of the hybrid
(digital/analog) HIPERFACE system. There is mere digital data transfer. DSL is short for

ink interface. The encoder signal and the power supply for the encoder are transmitted via
two lines and wired in the power connector.
Temperature sensor in the motor
3.2.4
The temperature of the stator windings in the winding heads of the motor must be recorded and
monitored by the servo amplifier. The monitoring system shall be designed to protect the engine to
temperature class F.
If an early warning temperature threshold is reached, an increased temperature is indicated. If this
temperature threshold is exceeded, the motor is switched off. This prevents thermal overload of the
motor in continuous operation.
For JetMove 2xx, a KTY-83-110 is installed as standard temperature sensor.
The PT1000 is the preferred choice for the new drive generation or motors with HIPERFACE
HIPERFACE DSL
®
encoders. For sizes JL1 and JHQ12 only a PTC is available as temperature
sensor. Motors with built-in thermostatic circuit breaker (140 °C) are only available as spare parts.
The built-in thermostatic circuit-breaker has a tolerance of ± 10 °C and can be operated up to a
maximum temperature of 150 °C.
Holding brake
3.2.5
All motors can also be supplied with a holding brake. If you apply DC 24 V to the holding brake, a
magnet winding is activated which counteracts the spring force of the brake by magnetic force and
thus cancels out the braking effect. The brake is a mere holding brake for keeping the motor shaft
at standstill. It is not designed for permanent slowing down the motor.
Gearings
3.2.6
Due to their standardized interface, all conventional speed reducers, such as planetary gear units,
can be attached to our servo motors. JetterAG offer a wide range of gearbox servo motors.
Further options
3.2.7
Other options for the motors can be supplied on request.
