Object 0x6042: vl_target_velocity

This object shall indicate the required velocity of the system. The value is given in
revolutions per minute (min
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."
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,

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.
8.1.7.

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.

Object 0x6046: vl_velocity_min_max_amount

This object indicates 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 vl_velocity_max value is 1500min
is 0min
Then, max value of speed is limited by
<example>
Motor pole number for communication (f856) = 2: 4 pole
Max value of speed = 3000min
Maximum frequency (fh) = 4 * 3000 / 120 = 100Hz
In the result, set fh to 100Hz.
