42 HX7+ ASD Quick Start Guide
4. Adjust Accel/Decel Automatically?
When enabled, the HX7+ ASD adjusts the
acceleration and deceleration rates according to the
applied load. The acceleration and deceleration
times range from 12.5 to 800% of the programmed
values [e.g., Acceleration Time 1 (F009) and
Deceleration Time 1 (F010) adjusted for the actual
Accel/Decel times used].
Settings:
0 — Disabled
1 — Enabled
The motor and the load must be connected prior to selecting Automatic Accel/Decel.
If Automatic Accel/Decel is not enabled, the Acceleration screen will appear followed by the
Deceleration screen as shown below.
5. Volts Per Hertz Setting
This function establishes the relationship between
the output voltage and the output frequency of the
ASD.
Settings:
0 — Constant Torque
1 — Variable Torque
2 — Automatic Torque Boost
3 — Sensorless Vector Control (speed)
4 — Automatic Torque Boost with Automatic Energy Saving
5 — Sensorless Vector Control (speed) with Automatic Energy Saving
6 — V/f 5-Point Setting (opens 5-point setting screen)
7 — Sensorless Vector Control (speed/torque switching)
8 — PG Feedback Vector Control (speed/torque switching)
9 — PG Feedback Vector Control (speed/position switching)
6. Motor Current Rating
This parameter allows the user to input the full-load
amperage (FLA) of the motor. This value is used by
the HX7+ ASD to determine the motor overload
protection setting for the motor. The value is found
on the nameplate of the motor.
