- Difference description concerning the Servo Drive 9400 HighLine from V5.0 to V7.0

Function extenstions
- Parametrisable exception handling
- Support for a second thermal sensor
- SB LS_EncoderX8: Encoder information from X8 available in application
- SB LS_ManualJogOpenLoop: Frequency-controlled manual jog (MOL)
- SB LS_PolePositionIdentification: Controls the rotor position adjustment via process signals (PLI)
- Persistent storage of the home status HM_bHomePosAvailable
- New mode, 'Position control', in code C2570
- New mode, 'Current controller optimisation with power pulse current', in code C0398
- Control of fans inside the device as a function of C0068
- Identification of a resolver error/Improvement of signal quality
- Expansion of system block LS_SyncInput
- Actual speed filtering for VFC with feedback
- Parameterisable error response to an overflow of the communication task

Eliminated function restrictions
- Triggering angular drift monitoring with absolute value encoders (removal of fault)
- Positioning operations in conjunction with limited speed (removal of fault)
- Deceleration not maintained with LS_Positioner with override (removal of fault)
- Positioning operations with a final speed and linear ramps (removal of fault)
- Digital frequency input/output drifts if the number of increments is not equal to 2^n (removal of fault)
- Keypad indicates 'Fatal Error: Necessary file 'keypad.cf' not found!' (removal of fault)
- SYNC_bSyncInsideWindow is not set correctly (removal of fault)
- Incorrect emergency telegram on the CAN bus (removal of fault)
- Incorrect motor parameter identification
- Inaccurate calculations for I^2xt monitoring of the brake resistor (removal of fault)
- Suppressed error message during identification run for determining a rotor position (removal of fault)
- DC-bus voltage filter time (removal of fault)
- SDO communication via CAN on board defective (removal of fault)
- Error on initialising EnDat encoder at X8 (removal of fault))
- Incorrect homing following project download (removal of fault))
- Despite changing from a position controller to an angle controller, 'Reference known' persists (removal of fault)
- Home position is lost when the mains power is switched off (removal of fault)
- No project download after program has been deleted via C0002 = 34 (removal of fault)
- Internal display limit for code C2532 (removal of fault)
