Operating Instructions
SIMOVERT MASTERDRIVES
P340 = ?
Enter the pulse frequency in kHz
Pulse frequency for asynchronous space vector modulation
Notes:
- The adjustable range depends on the converter/inverter
- An increase in the pulse frequency results in a reduction
of the maximum output current
(see "Technical Data", derating curves)
P350 = ?
Enter the reference value for all current quantities in A
(Normalization quantity for current limitations as well as current
setpoints and actual values) (see example in section 9.2.1)
P351 = ?
Enter the reference value for all voltage quantities in V
(Normalization quantity for voltage limitations as well as voltage
setpoints and actual values)
P352 = ?
Enter the reference value for all frequency quantities in Hz
(Normalization quantities for frequency limitations, frequency
setpoints and actual values) (see example in section 9.2.1)
Note: The parameter P353 is automatically adjusted.
Enter the reference value for all speed quantities in rpm
(Normalization quantity for speed limitations, speed setpoints
and actual values) (see example in section 9.2.1)
Note: The parameter P352 is automatically adjusted.
P353 = ?
P354 = ?
Enter the reference value for all torque quantities in Nm
(Normalization quantity for torque limitations, torque setpoints
and actual values) (see example in section 9.2.1)
P357 = ?
Enter the sampling time T0 in ms
The sampling time T0 is for determining the calculating
frequency of all functions.
The sampling times T1...T19 are multiples of sampling time T0
Note:
A very short sampling time T0 can lead to a calcu-
lation time overload if several function blocks are
activated at the same time!
