Ch.459
—————— Installation guidelines ——————
Requirements:
Sinusoidal encoders (XE connector on Regulation card)
max. frequency 80 KHz ( select the appropriate number of pulses
depending on required max. speed )
Number of pulses per revolution min 600, max 9999
Channels two-channel, differential
Power supply + 5 V (Internal supply) *
Load capacity > 8.3 mA pp per channel
Digital encoders (XE connector on Regulation card)
max. frequency 150 KHz ( select the appropriate number of pulses
depending on required max. speed )
Number of pulses per revolution min 600, max 9999
Channels - two-channel, differential
A/A,B/B,C/C
). An
encoder loss detection is possible via firmware setting.
- two channel, (A,B) only with optional card.
Power supply + 5 V (Internal supply) *
Load capacity > 4.5 mA / 6.8 ... 10 mA per channel
* Via keypad (“CONFIGURATION/Motor spd fbk/ Enc 1 supply vlt” menu) it is possible to select 4
different values of internal encoder supply voltage to compensate the voltage reduction due to encoder
cable length and load current encoder.
Selection available are:
- for +5 V encoder supply: 0=5.41V, 1=5.68V, 2=5.91V, 3=6.18V via Enc 1 supply vlt parameter.
- for +8 V encoder supply: leave standard default =0
Encoder power supply test (if the internal supply +5V is used)
During the start up of the drive:
- verify the encoder power supply to the encoders terminals with all the encoders channels connected
- via Enc 1 supply vlt parameter set the appropriate voltage if the encoder supply characteristic (example:
+5V ± 5%) is out of range.
Terminals for external encoder connections
Male terminals type: 15 poles high density (VGA type)
Connector cover: Standard 9 poles low profile (Example manufacturer code: AMP
0-748676-1, 3M 3357-6509)
