Code
Meaning Note
C0930 Gearbox factor - numerator, circumference of the pinion on
the motor side
Setting is only required if the actual value encoder is not
connected to the motor.
C0931 Gearbox factor - denominator, circumference of the pinion on
the encoder side
C0933 Calculating the position of the rising or falling edge of the zero
track or touch probe
Depending on the mode selected
C0934 Home position offset = Number of increments after the zero
pulse has occurred
The reference is: 65536 inc = 1 revolution. Selection is
possible up to 2140000000 inc
C0935 Maximum traversing speed Input in [%] of nmax C0011
C0936 Acceleration / deceleration time Linear ramp
C0926/3 REF-ACTPOS, actual position value Display only
C0926/4 REF-TARGET, actual target position Display only
The profile generator calculates the speed profile from the set profile parameters.
z The parameters can be changed during homing.
– C0935 and C0936 become active if REF-ON = LOW.
z The drive should not be driven at the torque limit (MCTRL-MMAX = HIGH), otherwise the drive
cannot follow the speed profile.
– Prolonging the acceleration / deceleration time until MCTRL-MMAX does not respond
anymore.
z The phase controller in the function block MCTRL must be active.
