Table 7.18 6048h vl_velocity_acceleration
7.4.9 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 will be generate 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.

7.4.10 604Ch vl_dimension_factor
The vl_dimension_factor configures the numerator and
denominator of the factor. The vl_dimension_factor serves
to include gearing in calculation or serves to scale specific
units of the user. It influences the vl_target_velocity,
vl_velocity_indexes.

7.4.11 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.

7.4.12 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.

Emergency Object
This section describes the general layout of the EtherCAT
emergency object. The emergency object is used to signal
error states in the frequency converters to the master. The
frequency converter can be programmed automatically to
send the EMCY object if an alarm or warning is activated.
The frequency converter resends the EMCY object if one of
the alarms or warnings is removed.
Communication Object Overview
The EMCY object always consists of 8 bytes data, see
