Product Description:

The CLM20.1-NP-120-NA-NNNN-NW is an Indramat position control module manufactured by Bosch Rexroth Indramat for the CLM Axis Positioning Control Modules series. It generates motion profiles, evaluates feedback, and distributes command signals to connected drive amplifiers so that mechanical axes follow programmed paths without relying on a separate PLC. Embedded software stores application code and parameters, allowing the unit to manage axis sequencing and motion behavior within the control platform. This arrangement supports machines that need coordinated positioning, repeatable travel, and direct interaction between the controller and the drive system.

Inside the controller, a SH4-compatible 32-bit processor executes interpolation loops for up to 2 axes in real time. It is supported by 16 MB of dynamic RAM for the operating system, user programs, and data buffers during high-speed path generation. Eight DC-isolated digital inputs capture limit switches, while eight isolated outputs energize contactors or status lamps and communicate control states to surrounding equipment. Power arrives through a 24 V DC feed, and the regulator remains functional down to 19.2 V so short dips do not trigger a reset. The housing carries an IP20 rating, which means the electronics resist finger contact but must be mounted inside a cabinet.

For applications that need larger I/O counts, an inline bus permits attachment of up to 63 expansion modules, bringing the usable field capacity to 256 points over a 32-byte process image. A removable CF card provides 128 MB of nonvolatile storage for application files, while operating parameters survive power loss in 64 kB of battery-free retentive memory. The compact enclosure measures 120 x 175 x 76 mm and weighs 0.858 kg, which helps the module fit into crowded control cabinets without adding much panel load. The unit can tolerate supply transients up to 30 V DC without damage, and no network interface is preinstalled, leaving fieldbus selection open for the target machine topology.
