Product Description:

The CSH01.1C-CO-EN1-EN2-MEM-NN-S-NN-FW is a single-axis controller from the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It serves as the command layer in drive systems, issuing position, velocity, and torque references to power sections while exchanging process data with PLCs and SCADA hosts. Within an automation cell, the module converts feedback from resolvers or digital encoders into motion commands that synchronize servo axes and peripheral devices.

This controller provides an analog test channel rated for 5 V, 1 mA output for quick signal verification, and it supports fieldbus communication over CANopen / DeviceNet for use in mixed-vendor networks. A discrete input turns on at 15 V, allowing direct connection to common 24 V sensing circuits through simple resistive dividers. The digital outputs can source up to 500 mA, enough to drive small contactors or status lamps without external amplifiers. Steady-state power draw is limited to 22.5 W, which helps reduce cabinet heat and eases supply sizing. Encoder emulation can deliver absolute or incremental signals, while two front-panel interfaces support feedback from a broad range of motors. Resolver / HSF is available on channel 1, and EnDat 2.1 / 1 Vpp / 5 V TTL is available on channel 2. A 100Base-TX engineering port provides access for setup and service communication.

The maximum cable length for the second encoder input with sense lines reaches 75 m, supporting remote motors without signal boosters. All user I/O pins share a common supply that may deliver up to 1.1 A, helping maintain stable logic voltage when multiple sensors switch at the same time. For legacy maintenance links, the integrated RS-232 port communicates at up to 115 kBaud. Two relay contacts are rated for 24 V DC, 1 A and can switch low-power brakes or interlocks. Resolver excitation is produced at 4 kHz with a carrier of 18.2 Vpp, supplying clean reference signals for high-speed position loops.
