Product Description:

The CSH01.3C-PB-ENS-MA1-CCD-NN-S-NN-FW motion logic control card is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into IndraDrive power sections and handles axis coordination within modular drive stacks. This arrangement separates the control layer from the power stage, so motion functions can be matched to the required drive hardware without changing the basic operating concept. By managing fieldbus traffic and real-time interpolation, the card links servo amplifiers to higher-level PLCs for deterministic motion control in packaging lines, pick-and-place stations, and material-handling cells. It also sends synchronized current, velocity, and position commands to connected drives so multiple axes can move in step during gantry and robotic operation.

The card’s supply overhead remains at 8.5 W, which helps keep internal heat generation low during operation. Control loops are refreshed every 62.5 µs, giving the servo amplifiers a fast update cycle for responsive torque control. For setup, the engineering interface supports 100Base-TX Ethernet and uses a shielded RJ-45, 8-pin socket for direct connection without media converters. Internal logic and encoder power are stabilized by an ENS rail that provides 11.6 VDC, isolating sensitive analog sections from bus transients. Two differential MA1 analog inputs accept ±10 V command signals, and a matching ±10 V output channel can feed external recorders, with both using 12-bit conversion. That analog capability allows the module to exchange reference and monitoring signals with external equipment when a machine uses mixed digital and analog interfaces.

During startup, the controller draws an inrush current of 4 A for as long as 100 ms, after which steady ENS consumption settles at 500 mA. The switching devices on the card can modulate drive carriers up to 16 kHz, which suits high-speed servo operation while helping reduce audible noise. Profibus communication reaches a maximum rate of 12 MBaud for cyclic data exchange between the controller and the network. A separate RS-232 monitor port operates at 115 kBaud over cables up to 15 m, providing a dedicated serial channel for status access. The serial monitor port is separate from the fieldbus channel, so network communication and local observation can remain independent.
