Torque ratios

The ratio between the torque of one axis group member and the torque of the remaining axis group members. The number of setting fields displayed depends on the number of subordinate axis group members. See also Torque ratios.

INFORMATION: The value does not have a unit, i.e. the information 50%: 50%, 2 : 2 or 3 Nm : 3 Nm have the same effect.

Index: 50011.1-4

IEC name: Controller.Config.TorqueRelation.lrAGMember1-4

Torque between axis group members

Torque difference (preload) between the respective axis group members in [%/nominal motor torque]. The number of setting fields displayed depends on the number of subordinate axis group members. See also Torque between axis group members.

Controller.Config.TorqueBetween.lrAGMember3_4

Controller.Config.TorqueBetween.lrAGMember4_1

Priority for the compensation: "Skew with/without overload guard" or "User-defined skew error"

Parameter designation

Description

Balance controller

Allow skew compensation

INFORMATION: Only visible in the "Skew with/without overload guard" operating mode.

  • Manual – Skew correction must be enabled in the IEC/fieldbus using xEnableSkewing.
  • With setpoints active – Skew correction starts automatically when the inverters switch to control.

Index: 50011.25

IEC name: Controller.MAC.Config.SkewLeveling.eEnableSkewing

P gain

Factor for increasing skew compensation

Index: 50011.18

IEC name: Controller.MAC.Config.SkewLeveling.lrPGain

Limit speed and limit deceleration for skew compensation

Limit the speed and deceleration of the "Skew priority" operating mode (lrSkewMaxMin and lrAccDecSkewMaxMin)

  • Not active
  • Active

Index: 50011.19

IEC name: Controller.MAC.Config.SkewLeveling.xVelDecLimiterON

  • Not active
  • Active

Index: 50011.20

IEC name: Controller.MAC.Config.SkewLeveling.xAccLimiterON

Maximum compensation acceleration/deceleration

 

INFORMATION: Only visible when limit speed and deceleration of skew compensation is active or limit acceleration of skew compensation is active.

Acceleration or deceleration limitation for skew compensation (in user units)

Default value: 10% of the "Acceleration/deceleration" application limit

Index: 50011.21

IEC name: Controller.MAC.Config.SkewLeveling.lrAccDecMaxMin

Maximum compensation speed

 

INFORMATION: Only visible with active limit speed and deceleration of skew compensation.

Default value: 10% of the "Speed" application limit

Index: 50011.22

IEC name: Controller.MAC.Config.SkewLeveling.lrVelMaxMin

Skew offset

Value

Position offset of the axis group members to the actual position of the axis group

Index: 50011.31-50011.34

IEC name: Controller.Config.SkewOffsetToMean.lrAGMemberX

Offset mode

Mode in which the set skew offset is implemented by the individual axis group members.

  • Forms actual position: If this setting is set for all axis group members, a symmetrical offset must be selected for the axis group. The sum of all the offsets is then 0. At least one axis must always form the actual position.
  • Moves offset: The axis group member travels the offset independently of the other axis group members.
