Onboard multiple preset speeds The system implements up to 16 speeds by using simple
PLC function or by using digital input signals.
Onboard PID The system implements the proportional-integral-
derivative (PID) function in the closed-loop control.
Automatic voltage regulation (AVR) The system maintains a constant output voltage automatically
when the line voltage changes through the allowable range.
Overvoltage and overcurrent
stall control
The system limits the output current and voltage automatically
during operation to prevent frequent or excessive tripping.
Torque limit and control The system limits the torque automatically to prevent
frequent overcurrent tripping during operation.
Torque control is applied in the CLVC mode.
Individualized
functions
High performance The MD500 applies control of an asynchronous motor by
using high-performance current vector control technology.
Power dip ride-through Load feedback energy compensates for any voltage
reduction, allowing the MD500 to continue to
operate for a short time during power dips.
Fast current limit The system applies fast current limiting techniques
to avoid frequent overcurrent faults.

DO) support simple logic control.
Timing control Time range: 0.0 to 6500.0 minutes
Dual-motor switchover The MD500 can control up to two motors. It controls one
motor at a time and then switches over to the other.

(PT100, PT1000) to implement motor overheat protection.
Multiple encoder types The MD500 supports a range of different encoder types:
ƕ Differential encoder
ƕ Open-collector encoder
ƕ Resolver
ƕ UVW encoder
User programmable function Option: The optional programming card supports secondary
development in a programming environment compatible
with the Inovance programmable logic controller (PLC).
