Unit Description
V Use this parameter to select the power supply voltage for the en-
coder.
– Use this parameter to set the reference signal on or off.
– Use this parameter to select the number of pulses per revolution of
the encoder.
– Use this parameter to select the number of pulses per revolution of
the proximity sensor.
% Use this parameter to select the duty cycle of the proximity sensor,
that is, the active/inactive signal ratio. Other ratios than 50% (1:1)
will decrease the supported maximum frequency of the proximity
sensor signals. This parameter is used to determine that the fre-
quency of the input signal will not exceed the detection capability
and cause pulses to be lost.
– Use this parameter together with Gear Ratio Multiplier to set the ra-
tio between the speed measured by an external sensor and the esti-
mated speed.
– Use this parameter together with Gear Ratio Divider to set the ratio
between the speed measured by an external sensor and the estima-
ted speed.
rpm Use this parameter to set the allowed deviation between the two
speed sources.
ms Use this parameter to set the time that the value of Allowed Devia-
tion of Speed Sources can be exceeded.
Unit Description
rpm Use this parameter to set the nominal speed that is used to define the ramp 1.
ms Use this parameter to set the minimum time for the speed to accelerate from zero to
Ramp1 Speed.
ms Use this parameter to set the maximum time for the speed to accelerate from zero to
Ramp1 Speed.
