Control Methods and Operation Modes
V/F Control Characteristics
The L200-040HFEF supports multiple voltage/frequency (V/f) control profiles to match various motor characteristics and load requirements:
- Constant Torque Mode: Suitable for conveyors, hoists, and other constant torque applications where torque remains constant regardless of speed variations.
- Reduced Torque Mode: Ideal for fans and pumps where torque requirements decrease proportionally with speed squared (affinity laws).
- Variable V/f Mode: Allows custom V/f curve programming for specialized motor or load characteristics.
Acceleration and Deceleration
The drive provides flexible speed ramping with the following options:
- Linear Acceleration/Deceleration: Standard ramp profile from 0.01 to 3000 seconds
- S-Curve Acceleration/Deceleration: Smooth ramping for loads requiring gentle speed transitions
- Second Acceleration/Deceleration: Alternative profile selectable via digital input (2CH terminal)
Built-in PID Controller
Unlike many inverters in its class, the L200-040HFEF features an integral PID control algorithm that enables closed-loop process control without external controllers:
- Process variable feedback via 4-20mA or 0-10V signal
- Programmable setpoint and feedback scaling
- Reverse PID function for heating/cooling applications
- Upper and lower frequency limits for process protection
- PID output preview signal (FBV) for multi-stage control
Run Command Sources
The L200-040HFEF offers three run command sources selectable via keypad DIP switch:
