SIMOVERT MASTERDRIVES Operating Instructions 9-41
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)
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)
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)
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)
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!
Thermal motor protection
desired?
System with motor protection according to UL regulation?
The motor temperature is calculated via the motor current.
(In the pre-setting, motor overload protection in accordance with
UL regulation is activated!)
no yes
P380 = ?
Enter the motor temperature for output of the alarm A023
"Motor overtemperature"
P381 = ?
Enter the motor temperature for output of the fault F020
"Motor overtemperature"
P382 = ?
Specify motor cooling
0: self-ventilated
1: forced-ventilated
P383 = ?
Enter the thermal time constant of the motor in s
