Determining the maximum number of MOVIMOT^® drives for group disconnection:

The number "n" of MOVIMOT^® MM..D drives that can be disconnected as a group is limited by the following factors:

• Switching capacity of the safety relay
• You must connect a fuse in front of the safety contacts according to the specifications of the safety relay manufacturer to prevent the contacts from welding together.
• It is mandatory to observe the information about the switching capacity according to EN 60947-4-1 and EN 60947-5-1 and the contact protection in the operating instructions of the safety relay manufacturer. Compliance with these specifications is the responsibility of the project planner.
• Maximum permitted voltage drop in the 24 V supply cable
• When configuring group drives, observe the values of the maximum cable lengths and the permitted voltage drops.
