Frequency Converter SD2B plus

The frequency converter SD2B plus allows sensorless operation of low-voltage asynchronous and synchronous motors with speeds up to 120,000 rpm, as well as control with TTL encoders.

Due to this motors can be operated speed-controlled and torque-controlled even from speed zero. The safety function Safe Torque Off (STO) is integrated as standard in the device to allow low-cost realization of the steadily increasing demands towards machine safety.

The NRTL/CSA certified devices are easily integrated into systems for the US market with no additional approvals needed.

Highlights

Master-Slave-Operation

Function:
Synchronization of several SD2B plus via TTL encoder inputs and outputs.

Advantage:
Autarkic high-precision synchronization of several SD2B plus frequency converters without external control components.

Benefit:
Lower system costs.
Integrated Logic Voltage Supply

Function:
NRTL/CSA certified.

Advantage:
Easier integration into machines for the North American market.

Benefit:
Lower costs, as no additional approvals are necessary
Parameterization via USB

Function:
Logic voltage supply via USB interface.

Advantage:
Parameterization of SD2B plus without connected voltage supply is possible via the USB interface, which allows pre-configuration of devices outside the machine.

Benefit:
Lower system costs.

The space marvel

The IP20 housing of the SD2B plus impresses with a reduced overall height of only 25 mm. The particularly compact design enables simple and flexible integration of the device. In addition to two TTL encoder inputs and outputs, there are five digital inputs/outputs each, an analogue setpoint input and a USB interface for easy parameterisation. All control sequences can also be displayed via the serial bus connections with CAN or RS232 implemented as standard.

Applications

High-speed spindles are the key components of a machine tool. Only when operated in an optimal way, the desired machining accuracy, productivity and service life of the whole machine is guaranteed.

Drilling, Routing
For dressing applications, it is essential to keep the spindle temperature low: a temperature increase in the spindle causes a longitudinal growth and therefore a shift of the tool position.
