The R911287036 (DKR04.1-W300N-BA03-01-FW) drive controller manufactured by Bosch Rexroth Indramat operates at a power voltage between 400 to 480 Volts and a system frequency of 50 to 60 Hertz. Its controlled voltage and power stand at 230 Volts AC and 300 VA respectively. The controller can digitally operate frameless spindle motors and linear LSF motors. Out-of-the-box, the R911287036 (DKR04.1-W300N-BA03-01-FW) adopts an external air cooling system but it can be altered to a different cooling mode before fitting it into a cabinet. With different power ratings, this device offers an array of options for efficient motor control. The R911287036 (DKR04.1-W300N-BA03-01-FW) drive controller, a member of the DKR product group, is integrated with a resolver and digital servo feedback system. The device is housed in a built-in heatsink to provide effective heat management. Necessary filters should be used in the air inlet to prevent overheating. The controller's command communication is executed via an analog interface. Boasting a 300 Amps of rated current, this device is designed to ensure no interference with high-frequency devices. Notably, the module does not include a bleeder. Lastly, the drive can be safeguarded from overvoltage disturbances using isolating transformers. This drive controller undergoes rigorous testing for consistent reliability and safe operation.
