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

C0926/4

REFC−TARGET, current target position

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.
