value
Description
Velocity DINT 0 Value of the maximum
velocity (not necessarily
reached) [user-dened
velocity unit]. Only values
>0 are allowed.
VAR_OUTPUT
InTorque BOOL Setpoint value of torque or
force equals the
commanded value.
Busy BOOL The function block is not
nished and new output
values are to be expected.
CommandA-
borted
BOOL Command is aborted by
another command.
Error BOOL An error has occurred
within the function block.
ErrorInfo DD_ERROR_ISD51x Error identication and
instance identier.
See chapter 6.5.2.3 Error
Indication.
Table 6.47 MC_TorqueControl_ISD51x
6.5.5.9 MC_GearIn_ISD51x
This function block commands a synchronized motion with
the master. The slave ramps up to the ratio of the master
velocity and locks in when this is reached. Any lost
distance during synchronization is not caught up. The
gearing ratio can be changed while MC_GearIn_ISD51x is
running, using a new rising edge of the Execute input.
After being InGear, the servo drive is running position-
controlled. Only positive values are allowed for the inputs
Acceleration and Deceleration. The value 0 is not allowed
for the inputs RatioNumerator and RatioDenominator.
The command is transferred and executed immediately.

gearing in [user-dened

equals the commanded

Table 6.48 MC_GearIn_ISD51x
6.5.5.10 MC_GearInPos_ISD51x
This function block commands a synchronized motion with
the master. It commands a gear ratio between the position
of the slave and the master axes from the synchronization
point onwards. Only values >0 are allowed for the inputs
Velocity, Acceleration, and Deceleration. The value 0 is not
allowed for the inputs RatioNumerator and RatioDeno-
minator.
The command is transferred and executed immediately.
