Operation With Pulse Encoder; Number Of Pulses Of Pulse Encoder (In Pulses/Revolution); Matching To Pulse Encoder Signal Voltage; Setting The Maximum Operating Speed For Pulse Encoder Operation (In Revolutions/Minute) - Siemens 6RA70 Series Instructions Manual

Operation with pulse encoder

5.2
P083 = 2:
P140 Selecting a pulse encoder type (pulse encoder types see below)
0 No encoder/"Speed sensing with pulse encoder" function not selected
1 Pulse encoder type 1
2 Pulse encoder type 1a
3 Pulse encoder type 2
4 Pulse encoder type 3
1. Pulse encoder type 1
P141

Number of pulses of pulse encoder (in pulses/revolution)

P142

Matching to pulse encoder signal voltage

0 Pulse encoder outputs 5 V signals (requires separate 5V encoder supply voltage)
1 Pulse encoder outputs 15V signals (uses internal 15V encoder supply voltage)
CAUTION
Resetting parameter P142 to the alternative 5V setting does not switch over the supply
voltage for the pulse encoder (terminals X173.26 and 27).
Terminal X173.26 always supplies +15V. An external voltage supply must be provided for
pulse encoders requiring a 5V supply.
P143

Setting the maximum operating speed for pulse encoder operation (in revolutions/minute).

The speed set in this parameter corresponds to an actual speed (K0040) of 100%.
Operation without tachometer (EMF control)

The actual speed is supplied by the pulse encoder (K0040)
Encoder with two pulse tracks mutually displaced by 90° (with or without zero marker)
Track 1
X173 28, 29
Track 2
X173 30, 31

The actual speed is supplied from the "Actual EMF" channel (K0287),
but scaled with P115.
EMF at maximum speed (Note: EMF = Terminal voltage – IxR)
1.00% to 140.00% of rated converter supply voltage at r071.
The actual value input is defined with P609.
Number of connector to which actual speed controller value is connected.
