Parameter 05.001 Output Frequency
Short description Displays the frequency applied to the motor
Mode Open‑Loop
Minimum −VM_SPEED_FREQ_REF Maximum VM_SPEED_FREQ_REF
Default Units Hz
Type 32 Bit Volatile Update Rate 4ms write
Display Format Standard Decimal Places 1
Coding RO, FI, VM, ND, NC, PT
If Enable Frequency Slaving (03.013) = 0 the Output Frequency (05.001) is the sum of the Post Ramp Reference (02.001) and the motor slip compensation frequency. If Enable Frequency Slaving (03.013) = 1 the Output Frequency
(05.001) is given directly by the Frequency Slaving Demand (03.001).
Parameter 05.002 Output Voltage
Short description Displays the r.m.s. line to line voltage at the a.c. terminals of the drive
Mode Open‑Loop
Minimum −VM_AC_VOLTAGE Maximum VM_AC_VOLTAGE
Default Units V
Type 16 Bit Volatile Update Rate 4ms write
Display Format Standard Decimal Places 0
Coding RO, FI, VM, ND, NC, PT
The Output Voltage (05.002) is the r.m.s. line to line voltage at the a.c. terminals of the drive.
Parameter 05.003 Output Power
Short description Displays the power flowing via the a.c. terminals of the drive
Mode Open‑Loop
Minimum −VM_POWER Maximum VM_POWER
Default Units kW
Type 32 Bit Volatile Update Rate 4ms write
Display Format Standard Decimal Places 3
Coding RO, FI, VM, ND, NC, PT
The Output Power (05.003) is the power flowing via the a.c. terminals of the drive. The power is derived as the dot product of the output voltage and current vectors, and so this is correct even if the motor parameters are incorrect and the
motor model does not align the reference frame with the flux axis of a motor in RFC-A mode. For Open-loop, RFC-A and RFC-S modes a positive value of power indicates power flowing from the drive to motor. For Regen mode a positive
value of power indicates power flowing from the supply to the regen drive.
Parameter 05.004 Motor Rpm
Short description Displays the estimated speed of the motor
Mode Open‑Loop
Minimum -180000 Maximum 180000
Default Units rpm
Type 32 Bit Volatile Update Rate Background write
Display Format Standard Decimal Places 0
Coding RO, FI, ND, NC, PT
If Enable Frequency Slaving (03.013) = 0 (normal operation) the frequency used to derive the Motor Rpm (05.004) is the Post Ramp Reference (02.001). If Enable Frequency Slaving (03.013) = 1 (frequency slaving operation)
the Frequency Slaving Demand (03.001) is used.
Motor Rpm (05.004) = 60 x Frequency / Pole pairs
where
Pole pairs = the numeric value of Number Of Motor Poles (05.011) (i.e. 3 for a 6 pole motor)
For frequency slaving operation there will be an error due to the motor slip frequency. For normal operation the result will be reasonably accurate provided that the slip compensation has been set up correctly.
Parameter 05.005 D.c. Bus Voltage
Short description Displays the voltage across the d.c. link of the drive
Mode Open‑Loop
Minimum −VM_DC_VOLTAGE Maximum VM_DC_VOLTAGE
Default Units V
Type 16 Bit Volatile Update Rate Background read
Display Format Standard Decimal Places 0
Coding RO, FI, VM, ND, NC, PT
D.c. Bus Voltage (05.005) gives the voltage across the d.c. link of the drive.
