However, support will also be provided by the service department of HEIDENHAIN Traunreut or by the nearest HEIDENHAIN agent. You will find the necessary telephone and fax numbers, as well as relevant e-mail addresses, on the back cover of the Service Manual, or on the HEIDENHAIN home page at http://www.heidenhain.de. Note It is extremely important to read also the general safety precautions on the following page, see page 1- 6.
Page 8: Safety Precautions
Improper treatment or use may cause considerable damage or injury to property or persons. HEIDENHAIN can accept no responsibility for direct or indirect damage or injury caused to property or persons through improper use or incorrect operation of the machine.
Page 9: Integral Monitoring System
Integral Monitoring System Introduction iTNC 530 features a comprehensive integral monitoring system for the prevention of input or operation errors, as well as for identification and diagnosis of technical errors on the control and the connected units. The monitoring system is an integral component of the iTNC hardware and software and is active as long as the control is switched on.

2.2.2 Nominal speed value monitoring For the axes, the nominal speed value monitoring is effective only in operation with velocity feedforward. For the spindle, it is effective in operation with following error as long as the position control loop is closed (orientation). If the nominal speed value calculated by the position controller is greater than the maximum possible nominal value, the blinking error message NOMINAL SPEED VALUE TOO HIGH <AXIS>...

Since the AC fail is reported to the control before the power fail, the control has more time to react to the subsequent dc-link voltage failure. Note Only the regenerative HEIDENHAIN inverter units provide the AC-fail signal. If a power fail is triggered on the control, all drives are brought to a controlled stop.
