Sensorless vector control (SLVC)
For higher performance on torque response and speed regulation the SLVC can be used. To use this mode the
motor parameter and the motor identification mode is required. No motor feedback is needed.
1. Set the motor control mode:
P300:0 to “Sensorless vector control [4]”
2. Advanced Motor setup:
Set motor parameter (6.5.12 Motor parameter, page 65) or select the motor out of the Lenze catalogue (In
case of a Lenze motor & Easy Starter).
NOTICE!
For the usage of SLVC the following restrictions apply:
 Only for asynchronous motors
 Only permissible for one single motor
 Not Permissible for hoists
 The connected motor may be maximum two power classes lower than the motor assigned to the invert-
er
Servo control (ASM)
Vector controlled servo control (with encoder) for asynchronous motors. Generally, the servo control offers the
same advantages as the sensorless vector control (SLVC) with increased speed regulation performance.
1. Set the motor control mode:
P300:0 to “Servo control ASM [2]”
2. Advanced Motor setup:
Set motor parameter (6.5.12 Motor parameter, page 65) or select the motor out of the Lenze catalogue (In
case of a Lenze motor & Easy Starter).
3. Encoder setup (6.5.16 HTL Encoder setup, page 67)
