ID 70208

Maximum acceleration too small (smaller 1 increment per cycle).

Description

The maximum permissible axis acceleration is set too low in the axis parameters (see P-AXIS-00008).

The position controller uses “0.1 µm per (cycle time)^2” as dimension of the maximum permissible axis acceleration (1 increment is equivalent to 0.1 µm for translatory and 0.0001° for rotary axes). The smallest representable acceleration value in the position controller is therefore “0.1 µm per (cycle time)^2” or “0.0001° per (cycle time)^2”. The acceleration specified in the axis parameters (dimension mm/s^2 or °/s^2) is converted into the position controller internal unit format. The acceleration value cannot be represented in the position controller if it is too small.

Specify larger value for maximum axis acceleration see P-AXIS-00008

or increase controller cycle time.
