JetMove 208-480 7.5 Sin-Cos Encoder Connection
Jetter AG 63
Important!
To be considered before connecting sin-cos encoders
If a sin-cos encoder is to be used, commutation finding always has to
be carried out after applying the logic power supply and before giving
the first enable.
If this is not considered, the motor might move uncontrollably.
The counting direction of the position in the JetMove 2xx is reversed in
the following cases:
Case 1: The signal sine+ is exchanged with the signal , and the
signal reference sine is exchanged with the signal reference cosine.
Case 2: The signal sine is exchanged with the signal reference sine.
Case 3: The signal cosine is exchanged with the signal reference
cosine.
Due to conduction loss, a voltage smaller than 5 V might reach the
encoder. If necessary, the encoder supply cords have to have a greater
diameter.
If a motor temperature sensor is not used, the inputs have to be short-
circuited at the adapter, so the JetMove 208-480 will not give an error
message.
