Gear ratio, axes 7-12
Description
The parameters XII and XIII define the gear ratio between the motor and the
external axes in question.
Menu
Resulting question from definition of external axis which has been defined as
independent external axis.
Guide text
LOW GEAR RATIO = (parameter XII)
HIGH GEAR RATIO = (parameter XIII)
Def.range
1-5000, resolution 1
Default value
Low gear ratio = 1
High gear ratio = 1
Note
The quotient between low and high transmission parameter must give a finite
numbers of decimals. It will results in error in the calculation algorithm.
Ex. Low/ High = 1/3 = 0.333 not working
Low/ High = 1/8 = 0.125 working
Velocity reference axes 7-12
Parameter XIV External drive unit axis 7-12.
Specifies which voltage level of the speed reference to the motor for the external axis
concerned, should correspond to the specified maximum speed.
Menu
Final question for axes 7-12 with external drive unit.
Guide text
MSREF(V) =
Def. range
0.0 - 9.4 V. NOTE! The speed reference voltage has a 12 bit resolution. With a
specified 9.4 Voltage level, a disturbance on the least significant
bit will result in a fluctuation in the speed reference. The
amplitude of the fluctuation will be appox. 5 mV. One should be
aware of this, especially in applications with low transmission gear
ratios.
Default value
9.4 V. (Do not enter a higher value than 9.4 V)

BRAKE
Description
The parameters Al to A12 are used to define whether the system robot axes and
external axes are equipped with mechanical brakes or not. The control system uses
the parameters to determine if the servo control should be deactivated or not when
BRAKE ON are activated.
