Optidrive P2 Advanced User Guide Rev 2.00
Optidrive P2 Parameter Set Overview
PM Motor Signal Injection Enable
Enables signal injection for use with PM motors. A high frequency signal is injected into the motor at a level defined by P7-17. The
information derived from this signal is then used to determine the motor speed more accurately when operating at low or zero speed,
improving operation without the need for a feedback encoder.
0: Disabled
1: Enabled During Magnetizing Period
2: Enabled During Low Speed Operation
3: Enabled During Magnetizing Period and Low Speed Operation
PM Motor Signal Injection Level
Sets the signal level used during the signal injection function in P7-17. If the value is too high, the drive may trip with over current.
0: Disabled
1 : Enabled. When enabled, over modulation provides a small increase in the available output voltage from the drive, which can assist
in applications where the supply voltage is too low to provide the required motor voltage, resulting in an increased motor current.
