Product Description:

The CDB01.1C-PB-ENS-ENS-ENS-ENS-S2-S-NN-FW is a modular drive control unit produced by Bosch Rexroth Indramat within the CDB Control Units series. Designed to plug into IndraDrive power sections, the module coordinates motion on multiple servo axes and integrates safety monitoring for factory automation lines. Its plug-in format keeps motion control, feedback handling, and safety functions within the same drive platform.

It manages up to 2 drive axes, letting a single control unit handle coordinated moves on adjacent mechanical stations. During standby it draws just 9 W of base power, which limits panel heat and auxiliary-supply sizing. Network exchange with higher-level PLCs takes place over PROFIBUS-DP, so telegrams for parameter download and cyclic setpoints flow on a standardized fieldbus. Four separate encoder inputs are available, and the designation 4 x ENS means each channel can accept a 1 Vpp sinusoidal encoder or a TTL encoder through a D-Sub 15 female connector. To energize those feedback devices, the unit provides an isolated 11.6 V supply rail, removing the need for external power taps. When the DC link is first charged, the control electronics withstand an inrush of 6 A, which must be considered in circuit protection.

Inrush duration is limited to 60 ms, keeping the surge brief enough for standard semiconductor fuses. Digital reference pulses on the ENC inputs can be counted up to 400 kHz, giving headroom for high-resolution linear scales at elevated traverse speeds. Serial diagnostics are accessible through an 8-pin Mini-DIN RS-232 port that supports a maximum baud rate of 115 kBaud, which is adequate for parameter backup and diagnostic communication. The control card routes fieldbus wiring through a D-Sub 9 female plug, while a second 9-pin socket carries Safe Motion signals with 1.6 A capability. The connectors are arranged on the control card for cabinet wiring without separate terminal blocks.
