Replacement Instructions for Smart Controller Drives
The following describes how to replace the drive in Schindler Smart controllers with a YASKAWA L1000A AC
drives for Lift. This solution has been developed to replace drives used in Smart MRL 001 / 002 controllers.
◆
Requirements
The L1000A can almost directly replace existing drives. The only additional component needed is an external
relay to control the brake.
YASKAWA recommends a relay from the 46.52 series made by Finder. When other relays are used it should be
selected so that the excitation current of the coil does not exceed the specifications of the output M2 on the
L1000A drive. Generally the relay should be selected so that the excitation current is as low as possible.
