SINAMICS G120 Control Units CU240S, Edition 05/2007
Note: P1300 = 1 : V/f with FCC (flux current control)
• Maintains motor flux current for improved efficiency.
• If FCC is chosen, linear V/f is active at low frequencies.
P1300 = 2 : V/f with a quadratic characteristic
• Suitable for centrifugal fans / pumps
P1300 = 3 : V/f with a programmable characteristic
• User defined characteristic (see P1320)
• For synchronous motors (e.g. SIEMOSYN motors)
P1300 = 5,6 : V/f for textile applications
• Slip compensation disabled.
• Imax controller modifies the output voltage only.
• Imax controller does not influence the output frequency.
P1300 = 19 : V/f control with independent voltage setpoint
The following table presents an overview of control parameters (V/f) that can be modified in relationship to P1300
dependencies:
Sensorless vector control (SLVC, P1300 = 20,22):
SLVC can provide excellent performance for the following types of application:
• Applications which require high torque performance
• Applications which require fast respond to shock loading
• Applications which require torque holding while passing through 0 Hz
• Applications which require very accurate speed holding
• Applications which require motor pull out protection
