CHAPTER5 CANOPEN COMMUNICATION FUNCTION

5.1.10 vl_target_velocity (Index: 6042h)

The vl target velocity is the required velocity of the system. It is multiplied the vl dimension factor and the vl set-point factor, if these are implemented.

Inverter parameter = output frequency setting (Multi-speed0) (A020) (unit: min-1Minimum unit: 1dig= 1min-1)

5.1.11 vl_velocity_demand (Index: 6043h)

The vl velocity demand is the instantaneous velocity provided by ramp function, scaled to the unit of the vl target velocity.

Inverter parameter = output frequency monitor (d001) (unit: min-1Minimum unit: 1dig= 1min-1)

5.1.12 vl_velocity_effort (Index: 6044h)

The vl velocity effort is the velocity at the motor spindle or load, scaled to the unit of the vl target velocity.

(unit: min-1Minimum unit: 1dig= 1min-1)

5.1.13 vl_velocity_min_max_amount (Index: 6046h)

The vl velocity min-max amount index is composed of the vl velocity min(Sub-index1) amount and vl velocity max(sub-index2) amount sub-index. (32bit length)

Sub-index1 = 1st frequency minimum limiter (A062) Sub-index2 = 1st frequency maximum limiter (A061) (unit: min-1Minimum unit: 1dig= 1min-1)
