If a value of 0 mm/s
3
is set in any of the jerk parameters, this section of the profile will be linear i.e. jerk = acceleration or deceleration rate.
A40 (Acceleration Rate G11)
A41 (Deceleration Rate G12)
These are the acceleration and deceleration rates set in mm/s
2
. The acceleration rate is also used during start optimization if constant acceleration is
reached.
The acceleration rate defines the linear ramp rate and is applied when the frequency / speed is changing away from zero. Selecting a ramp rate that
has been set to zero in Open-loop mode disables the ramp system in order that the post ramp reference follows the pre-ramp reference without any
delay in acceleration or deceleration. This also disables the standard ramp DC link voltage controller and the frequency based current limits.
A42 (Creep Stop Deceleration G17)
This is the final positioning deceleration rate from Creep speed to a stop and is set in mm/s
2
. This deceleration rate can be set higher than the main
deceleration rate to improve final positioning ride comfort and accuracy in creep to floor operation.
A43 (V1 Creep Speed G01)
A44 (V2 Speed Reference G02)
A45 (V3 Speed Reference G03)
A46 (V4 Speed Reference G04)
Operating speed V1 has been defined as the creep speed which sets the operating speed during creep for and creep to floor operation set-up in
mm/s. For creep to floor operation V1 is allocated as the creep speed by default. Other speed references may be selected to be creep speed via
Creep Speed Select (G52). Operating speeds V2, V3 and V4 and above are open for allocation by the user and are set-up in mm/s. The naming
strategy used can be changed to suit the system and required operating speeds, for example V2 Low speed, V3 Contract speed or V4 High speed.
A47 (Brake Control Release Delay D04)
A48 (Brake Control Apply Delay D05)
The brake release delay sets the time in ms for the brake to be fully released / opened on the motor. This is used during starting to determine when
the brake is considered fully released / open prior to disabling any start optimization, and starting the travel profile. This time is also taken into
consideration for the brake contact monitoring. For Open loop operation, the brake release delay must allow for the slip of the induction motor in order
to ensure sufficient torque can be generated on brake release (Brake release delay ~ Motor output frequency > Motor slip).
