Table A- 3 New functions and function changes in Firmware 4.7
1 Supporting the identification & maintenance datasets
✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓
2 Fall in pulse rate with increased drive power required by the
motor
• The inverter temporarily lowers the pulse frequency if
required when the motor is started up, and simultaneously
increases the current limit.
✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓
3 S7 communication
• Direct data exchange from the inverter and human machine
interface (HMI)
• Increase in communication performance with the
engineering tools and support of the S7 routing
✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ -
4 The basic functions of Safety Integrated are unrestrictedly
available in all control types with 1FK7 encoderless permanent-
field synchronous motors

5 Direct selection of the 1FK7 encoderless permanent-field
synchronous motors using the order number with allocated
code number
• It is not necessary to input individual motor data
- - - - - - ✓ - -
6 Pulse input as source of setpoint value
• The inverter calculates its speed setpoint from a sequence
of pulses at the digital input.

7 Dynamic IP address assignment (DHCP) and temporary device
✓ ✓ ✓ - ✓ ✓ ✓ ✓ ✓
PROFIenergy Slave profile 2 and 3
9 Uniform behavior for component replacement
• After a component is replaced, an inverter with activated
Safety Integrated will report what type of component has
been replaced using a unique code.
