Actual speed sensing data

7.6.5.1

Operation with pulse encoder

(often present when retrofitting existing systems)
P083 = 2: The actual speed is supplied by the pulse encoder (K0040)
P140 = 1. Pulse encoder type 1
Encoder with two pulse tracks mutually displaced by 90°
Track 1
X173 28, 29
Track 2
X173 30, 31
P141 Number of pulses of pulse encoder (pulses per revolution)
P142 = 1: Pulse encoder outputs 15V signals
NOTICE
Resetting parameter P142 to the alternative 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 speed for pulse encoder operation (in pulses/rev)
The speed set in this parameter corresponds to an actual speed (K0040) of 100%.
7.6.5.2

Operation with analog tacho

(used in new systems)
P083 = 1: The actual speed is supplied from the "Main actual value" channel (K0013)
(terminals XT.103, XT.104)
P741 Setting of tachometer voltage at maximum speed (approx. 8V to +270.00V)
7.6.6

Speed setpoint data

7.6.6.1 Operation with analog setpoint (U251=0)
P700 = 0: Voltage input (+-10V)
1: Current input (0 to 20 mA)
2: Current input (4 to 20 mA)
P401 Normalization
speed setpoint that must be attained under control by master switch (in %).
with lifting gear: approx. 60%
with travel gear: up to 100%
Note: Limit value for zero-delay angle (U628), see also Section 7.6.14
7.6.6.2 Operation with 4 stage master switch (U251=1)
U251=1: Use setpoint of 4-stage master switch
U665 speed setpoint in "slow" stage
U666 speed setpoint in "medium" stage
U667 speed setpoint in "fast" stage
U668 speed setpoint in "full" stage
