Digital 4-Q servo amplifier for brushless motors with resolver

Digital servo amplifier MDR230/4-6S

MDR 230/4-6S

The established digital amplifier MDR 230/02 SR was refined according to the customer's requirement. A new amplifier was developped, able to solve applications without further controls.

Digital amplifier with 4Q-operation and constant transfer
Torque, speed or position control with short cycle times
CAN-communikation and RS232
Optional technology slot, e.g. Profibus module
64 storable positions, integrated positioning programme with up to 32 positions
Incremental encoder output/input, output selectively as RS422 format or HTL 24 V A + B trace, programmable number of lines
Rotor encoder feedback by resolver
Comfortable parameterising software, e.g. oscilloscope function
