Communication Profile Area
6.4.9 6048h vl_velocity_acceleration
The vl_ velocity_acceleration index specifies the slope of
the acceleration ramp. It is generated as the quotient of
the delta_speed and delta_time. The Delta time is stored
in 3-41 Ramp 1 Ramp Up Time, and the Delta speed is store
locally in the options non volatile memory. After a power
down the delta speed will be generated from the
frequency converter 1-25 Motor Nominal Speed. This can
give a different readout from the frequency converter, but
the slope value is maintained.

6.4.10 6049h vl_velocity_deceleration
The vl_ velocity_deceleration index specifies the slope of
the deceleration ramp. It is generated as the quotient of
the delta_speed and delta_time. The Delta time is stored
in 3-42 Ramp 1 Ramp Down Time, and the Delta speed is
stored locally in the options non volatile memory. After a
power down, the delta speed is generated from the
frequency converter 1-25 Motor Nominal Speed. This can
give a different readout from the frequency converter, but
the slope value is maintained.

6.4.11 6060h Modes of Operation
This index is used for selection the Danfoss FC profile,
MCO profile, or the DS 402 profile. The index links directly
to 8-10 Control Word Profile. If this value is changed while
in operation, the option enters the "Error PREOP" state.

6.4.12 6061h Modes of Operation Display
This index is used to display which mode the frequency
converter is in. The mode can be changed via index 6060.
The values are the same as used for index 6060.

Converter Mode
This index informs the user of which operating mode the
frequency converter is capable of. Bit 1 is set, indicating
that the frequency converter can run DS 402 velocity
mode, bit 16 FC profile and 17 indicates MCO profile.
6.4.14 6504h Frequency Converter
Manufacturer
This index does readout the name of the frequency
converter manufacturer. Data is coded as a string.
