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.
