Product Description:
The VCH02.1NNN-000RS is an operator handwheel module from the VCH IndraControl Terminals series produced by Bosch Rexroth Indramat. The unit is intended for manual jog, teach-in, and override tasks on CNC- or PLC-controlled axes, allowing the user to send incremental pulses directly to the drive while receiving tactile feedback from the built-in wheel. By integrating a compact encoder, pushbutton contacts, and logic-level outputs, it bridges operator input and motion hardware in machine tools, packaging lines, and assembly cells.
The electronics are powered from an operating rail of DC 5 V ±0.25 V, and total current draw stays below 150 mA maximum, so the terminal can be supplied from standard controller backplane regulators without an extra power supply. Two dry-contact paths handle auxiliary commands; one is rated for 220 VAC at 0.5 A maximum, while the second channel manages low-voltage loads up to 30 VDC at 1 A maximum. Logic outputs remain stable because the high signal threshold is 2.5 V and the low threshold is 0.5 V, ensuring clear state discrimination when only 20 mA of input current is available. Pulse trains leaving the encoder remain within 5 kHz maximum, which matches the interrupt capabilities of common motion cards and protects downstream opto-isolators from excessive toggling. An axial bearing supports up to 10 N so that inadvertent pressure on the wheel does not disturb pulse accuracy.
The unit also supports a radial load ceiling of 20 N, a handwheel speed limit of 200 rpm maximum, and a signal transition rise or fall time of 200 ns to keep edge jitter low during rapid jogging. During transport or emergency stops, the housing tolerates shocks up to 980 m/s² for 6 ms without encoder misalignment. The complete assembly weighs only 0.65 kg, making it suitable for pendant mounting on light swing arms.
