5.6.8. Electronic gearbox (MC_GearIn)
FB name MC_GearIn
Controlled speed and position synchronicity with adjustable transmission ratio
VAR_IN_OUT
Master
INT
Constant for the master signal source (see page 161)
Config
uration (see page 82) of the signal sources
Please note:
The auxiliary axis can only be coupled to the position
setpoint value of the main axis => if Slave = auxiliary
axis, the main axis must be the Master.
The reduction ratio is then fixed to 1:1.
Slave
INT
VAR_INPUT
Execute
BOOL Starts the sequences of the module with positive edge
RatioNumerator
REAL
Reduction ratio numerator
Field is only valid, if Slave=AXIS_REF_LocalAxis (main
axis).
RatioDenominator
INT
Reduction ratio denominator
Field is only valid, if Slave=AXIS_REF_LocalAxis (main
axis).
Acceleration
DINT
Value of acceleration / deceleration (always positive) until
the synchronism is reached [Units/s²] <value range> (see
page Fehler! Textmarke nicht definiert.)
VAR_OUTPUT
InGear
BOOL Synchronicity achieved
CommandAborted
BOOL Command aborted
Error
BOOL Error while executing module
Note:
 Behaviour: the drive accelerates (with Acceleration) until the master speed is
reached - the module will report synchronicity with "InGear". Position losses
during acceleration to master speed are not made up.
 The transmission ratio can be changed at any time with a positive edge on
Execute. InGear is reset until synchronicity is achieved again.
 For example, if speed synchronicity is not achieved because of limiting effects,
the position difference that arises will be made up (by the active position
controller).
 Acceleration / deceleration to the set transmission ratio takes place without a jerk
limit.
 If the master and slave units do not correspond, this fact must be considered for
the transmission ratio.
