4.3.4 Kneeshaped acceleration characteristic curve
4.3.4.1 Activation
Key statement
The example given illustrates how the knee-shaped acceleration characteristic curve is activated on the basis of:
• Machine data
• Part program instruction
Machine data
• Parameterizing the characteristic curve (example only)
• Activation by setting as the channel-specific default setting
