Synchronous motors (PMSM) – Manual with installation instructions 2.3 Description 2.3.1 Rotary encoders (option: IG, MG) Rotary encoder with zero track (option: IG) Depending on the application and customer requirements, a variety of rotary encoders are used. If possible, these encoders are adjusted by NORD. If this is not possible, an offset is determined and stated on a sticker inside the terminal box. -
Page 19: Requirements For The Use Of The Drive
2 Description of the drive 2.4 Requirements for the use of the drive 2.4.1 Ambient conditions The motor must be protected against intensive sunlight, e.g. by the use of a protective cover. The insulation is tropicalised. Installation altitude: maximum 1000 m Ambient temperature: -20°C to +40°C For standard motors (without options), an extended ambient temperature range from -20°C to +60°C is permissible. -
Page 20: Frequency Inverters And Encoders
Synchronous motors (PMSM) – Manual with installation instructions 2.4.4 Frequency inverters and encoders The motors must only be operated with suitable frequency inverters. For energy-efficient operation, the frequency inverter must detect the position of the rotor. For this, different options with and without an encoder are possible, see also TI60_0010. -
