1. Description
The BLD 5603 and the BLD 5606 are 4-quadrant PWM servo ampliers suitable for the
three-phase brushless DC-servomotors, type 2036, 2444, 3056 and 3564.
The Servo Ampliers use a combination of SMD (Surface Mounted Device), MOSFET power
stage and PWM (Pulse-Width Modulation) technologies to achieve both, compact design and
high power efciency.
The basic board of the servo ampliers is a single level PCB structure, which performs all
the commutation and protective functions and contains the power stage mounted on the
heat sink plate.
The ampliers are available in two different function modes: Current control and Speed
control.
Current control (basic boards)
- BLD 5603-CC4P or BLD 5606-CC4P
In the ampliers the current owing in the active phases of the motor is regulated by the
analog current command. The ampliers are designed for use with a position controller or
in constant torque applications.
Speed control (two amplier congurations are available)
– BLD 5603-SH4P or BLD 5606-SH4P > the type SH4P uses the Hall sensor signals of the
brushless DC-servomotor to allow precise regulation at speed above 1000 rpm.
– BLD 5603-SE4P or BLD 5606-SE4P > the type SE4P is able to regulate at much lower
speeds, depending on the encoder resolution. Typical speed with 500 line encoder down
to 20 rpm.
These two servo ampliers consist of the basic board with optional modules.
These modules have a special frequency-to-voltage converter, allowing accurate
motor speed control and are provided with a current limiter function, type I2t.
The maximum continuous output power without additional heat sink is 220 W.
For ease of installation a loose female terminal block is supplied together with the main
board connector.
