Resolver General Each of the interface cards delivered by KEB include two interfaces. As there are numerous different combinations available each interface will be described by means of separate instructions. The instruction covers the installation of the interface card, the connection as well as the start-up of a suitable encoder.
Resolver at channel 1 Mechanical installation All kind of works on the inverter may be carried out by authorized personnel in accordance with the EMC and safety rules only. • Switch inverter de-energized and await capacitor discharge time • Pull off operator • Remove plastic cover •...
Resolver at channel 1 3.1.3 Input signals channel 1 3.1.3.1 Signal tracks A sine-wave voltage is output at terminals REF_HI and REF_LO at the resolver interface. This voltage supplies the field winding in the resolver. This signal is transmitted via a rotary transformer to the rotary part of the resolver. The pulsating magnetic field induces electrical voltages in the two signal windings which are shifted about 90°. The voltages pulsate with the same frequency and phase position as the field signal. However their amplitudes are depending on the position of the rotor winding.
Temperature range constant up to 80 °C Color green RAL 6018 3.1.6 Encoder line length The maximum line length of the encoder cable is 50 m. Please contact KEB if longer enco- der cables are required. GB-8...
Resolver at channel 1 3.1.7 Tested encoders The following resolvers have been tested by KEB on it application: • Tamagawa TS 2620 N21 E11 (default) • Tamagawa TS 2641 N11 E64 • LTN RE-15-1-A14 • LTN RE-21-1-A05 • Harowe 10BRCX 401 k1C However, this does not restrict the use of rotary encoder with same specifications of other manufacturers. Channel 2 The description of input X3B is depending on the used encoder interface. It is described in a separate manual.
Resolver at channel 1 Special resolver The use of 2-pole resolvers (pole-pair number 1) is provided as standard. If a resolver with another pole-pair number shall be used, the pole-pair number is to be used as gear factor. Gear factor denominator –––––––––––––––––––––...
