EMC considerations
The TMCM-1210 contains ferrite beads on-board in line with the positive supply input and all 4 motor windings
connections in addition to filter capacitors.
Tests have shown that it is possible to meet Class B emission standards using the bare TMCM-1210 (motor and
power connected) with the motor running slowly at maximum current (0.7A RMS) and +24V supply voltage without
additional / external filters.
Figure 8.1: Setup with TMCM-1210 and attached motor (motor rotating slowly @ 0.7A RMS / 24V supply, stand-
alone mode using on-board TMCL-autostart-program)
Figure 8.2: measurement results (example)
Please note that these measurement results using a bare TMCM-1210 unit with only motor and power supply
connected do not imply any guarantee for a complete system with one or more integrated TMCM-1210 with
meeting any emission limits.
