Hardware setting of the STEVAL-IHM025V1

The STEVAL-IHM025V1 demonstration board can be driven through the J4 motor connector

by various control units released by STMicroelectronics. The demonstration board is

suitable for field oriented control as well as for tachometer or hall sensor closed-loop control.

The STEVAL-IHM025V1 demonstration board ideally fits with STMicroelectronics’ released

STM3210B-EVAL board based on the STM32 MCU family as the control unit for FOC-

driving algorithms.

Hardware settings for six-step (block commutation) current

control - single-shunt configuration

To drive any motor, the user must ensure that:

●

The motor control demonstration board is driven by a control board that provides the

six output signals required to drive the 3-phase power stage

●

The motor is connected to the J2 motor output connector

●

If using an encoder or hall sensor connection, it is connected to connector J5

●

If using a tachometer connection, it is connected to connector J7

●

If using a dissipative hardware brake connection to a related dummy load, it is

connected to connector J6.

Table 2 below shows the jumper settings for any motors. Please confirm that the

demonstration board input voltage (mains voltage) is in the range of 125 VDC to 400 VDC or

90 VAC to 285 VAC.
