Answer : The reason could highly be due to the C-ON input (All windings On input), this input is normally open. Please do ensure that the C-ON input is connected to closed. After which a simple way to check whether this has been connected properly would be to try rotating the rotor of the motor, with the C-ON input closed, the rotor should not be able to rotate.
*In this case, the motor being used is not an electromagnetic brake type. If it is, please do ensure that 24VDC is supplied to the electromagnetic brake, as it is a power off activated braking mechanism.
