Did the OP have some Hal circuitry that depended on it maybe? He appears to want to set it from HAL. (Because he has one VFD connected to either of two motors, I think for either a low speed (50Hz) or high speed (400Hz) spindle.
Many VFD motor-configuration registers, including PD005 "Maximum Operating Frequency", can be set by hy_vfd at startup based on command-line arguments. None of them can be changed at runtime via HAL pins.
