6.1.6. Object 0x6042: vl_target_velocity
This object shall indicate the required velocity of the system. The value is given in
revolutions per minute (min
-1
). Positive values forward direction and negative values
indicate reverse direction.
At changing to “Operation enable” state, this target velocity is cleared. So set this target
velocity data after changed the state to “Operation enable.”
Warning
Mandatory
action
This object value is depending on the f856 parameter and confirms it setting value.
The motor rotational speed of the forecast is not obtained when the setting is mistaken,
and there is danger of causing the accident etc.
6.1.7. Object 0x6043: vl_velocity_demand
This object provides the instantaneous velocity generated by the ramp function. It is an
internal object of the drive device. The value is given same unit as the vl_target_velocity.
Positive values indicate forward direction and negative values indicates direction.
6.1.8. Object 0x6044: vl_velocity_actual_value
This object provides the velocity at the motor spindle or load. Depending on the
implementation (simple drive device, without sensor, etc.), the drive provides the
appropriate image of the actual velocity (velocity demand, velocity control effort,
calculated velocity).
The value is given in the same unit as the vl_taget_velocity. A positive value indicates
forward direction and negative values indicates reverse direction.
6.1.9. Object 0x6046: vl_velocity_min_max_amount
This object indicates the configured minimum and maximum amount of velocity (unit
min
-1
). The vl_velocity_max amount sub-object is mapped internally to the
vl_velocity_max positive and vl_velocity_max negative values. The vl_velocity_min
positive and vl_velocity_min negative values.
At initial configuration, the Upper limit frequency (ul) and Lower limit frequency (ll) of
the drive may be not same value with Object 0x6046 setting value. And when changes
the upper limit frequency and the lower limit frequency of the drive parameter, Object
6046 value is different with the drive parameters. To correspond these limit value, set
Object 6046.
