P3.7.7 RAMP TIME FACTOR (ID 518)
Use this parameter to set the multiplier of the selected ramp times when the output
frequency of the drive is between the prohibited frequency limits.
The Ramp Time Factor sets the acceleration and the deceleration time when the output
frequency is in a prohibited frequency range. The value of the Ramp Time Factor is multiplied
with the value of P3.4.2 (Acceleration Time 1) or P3.4.3 (Deceleration Time 1). For example,
the value 0.1 makes the acceleration/deceleration time ten times shorter.

LIMIT SUPERVISIONS
P3.8.1 SUPERVISION #1 ITEM SELECTION (ID 1431)
Use this parameter to select the supervision item.
The output of the supervision function can be selected to the relay output.
P3.8.2 SUPERVISION #1 MODE (ID 1432)
Use this parameter to set the supervision mode.
When the 'Low limit' mode is selected, the output of the supervision function is active when
the signal is below the supervision limit.
When the'High limit' mode is selected, the output of the supervision function is active when
the signal is above the supervision limit.
P3.8.3 SUPERVISION #1 LIMIT (ID 1433)
Use this parameter to set the supervision limit for the selected item.
The unit shows automatically.
