Fig. 3−148 Homing speed profile
Code Meaning Note
C0930 Encoder/gearbox factor − numerator (motor speed) Setting only required if the actual value encoder is not
mounted to the motor
C0931 Encoder/gearbox factor − denominator (encoder speed)
C0933 Selection of the edge of the touch probe signal at X5/E4 The touch probe edge provides the bench mark for the home
position offset to the homing modes that include touch probe.
C0934 Home position offset = number of increments after zero pulse Reference: 65536 inc = 1 revolution. Max. entry: 2140000000
inc
C0935 Homing speed Input in [%] of nmax (C0011)
C0936 Homing acceleration time, homing deceleration time Linear ramps
C0926/3 REFC−ACTPOS, actual position value Read only
C0926/4 REFC−TARGET, current target position Read only
The profile generator calculates the speed profile from the set profile parameters.
l The parameters can be changed during homing.
– C0935 and C0936 become active if REF−ON = LOW.
l 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.
l The angle controller in the MCTRL function block must be activated.
