# Dimensions identifiers

The following identifiers have been introduced to simplify the presentation of diagnostic values:

Flag | Description | Example
0 | Dimensionless No dimension is available for the value provided. | Index, internal computing quantity
1 | Position in 0,1 µm or 0,0001 ° | Travel over a software limit switch
2 | Velocity in µm / s or 0,001 ° / s | Programming of a negative speed
3 | Acceleration in mm / s^2 or ° / s^2 | Acceleration exceeds the maximum permitted axis acceleration
4 | Jerk in mm / s^3 or ° / s^3 | Exceeding of the maximum permitted axis jerk
5 | Time in µs | Inadmissible assignment of the cycle or ramp time
6 | Percentage as a percentage factor with in 0.1 % | Negative percentage acceleration weighting specified
7 | Address | Inadmissible address, access to address
8 | Increments The value is a position in the dimension increments. | Inadmissible grid of the compensation value intervals in the case of SSFK
9 | Feed rate per revolution in 0.1 µm / rev. | Programmed feed rate per revolution low small
10 | Cutting speed in µm / s | Programmed cutting speed too small
11 | Path resolution in increments / 0.1 µm | Current path resolution of an axis
12 | Increments per revolution The value is the number of increments per revolution, the measurement system is providing | Feed forward control of profibus drives
13 | Byte The value is the minimum number of bytes required for certain functionalities. | Configurable memory for forward-/backward on path
14 | Proportional gain | Kv-factor in the position control loop
15 | Frequency in Hz | Filter cut off frequency is zero (nil).
16 | Motor load in kg or kg*m^2 | Invalid value for motor load.

The specified units can be used to display error messages.
