Explanation
Displays the actual rotation speed of the motor
shaft.
Calculates and displays the present value of the
mechanical axis based on feedback from the mechanical axis based on feedback from the
motor sensor.
Displays the mechanical axis position
referenced by the Position Driver. referenced by the Position Driver.
Displays the deviation of the present value from
the reference value with encoder/resolver the reference value with encoder/resolver
resolution.
---
Calculates and displays the movement speed of
the mechanical axis based on feedback from the mechanical axis based on feedback from
the motor sensor.
---
---
Displays the output current to the motor.
Displays the effective load factor with respect to
the motor's rated current value.
Effective load factor = (output current effective
value) / (motor's rated current)
Effective values are calculated at the time
interval set for HP-33 (load factor time
constant).
Calculates the motor's heat generation from the
output current and displays it as a percentage
of the heat generation in rated operation. (When
the power is turned ON, 90 [%] is displayed.) If
this value exceeds 110 [%], an A.L17 (motor
overload) alarm will be detected.
Displays the motor's electrical angle (0.0 to
360.0).
When a Regeneration Resistor is connected,
this monitor item displays the regenerative
absorption current as a percentage of the
motor's rated current.
