6.10.2 Level 1 parameters

Text after a block of parameters refers to the preceeding parameter(s).
NOTE
No. Function
Minimum speed
01
Used to set minimum speed at which the motor will run.
(0V reference or minimum scale current input [see parameter 16] represents the value
in parameter 01)
No. Function
Maximum speed
02
Sets the maximum speed at which the motor will run in both directions of rotation. If
parameter 02 is set below parameter 01, parameter 01 is automatically set to the new
value of parameter 02. (+10V reference or full scale current input [see parameter 16]
represents the value in parameter 02).
The output speed of the drive can exceed the value set in parameter 02 due to slip
NOTE
compensation and current limits.
No. Function
Acceleration
03
rate
Deceleration
04
rate
Sets the acceleration and deceleration rate of the motor for both directions of rotation.
The acceleration rate corresponds to the time to accelerate from 0 to 100Hz. Therefore,
with a programmed ramp time of 5 seconds, the ramp output will reach 50Hz from 0Hz
in 2.5 seconds.
The deceleration rate corresponds to the time to decelerate from 100 to 0Hz.
Therefore, with a programmed ramp time of 10 seconds, the ramp output will reach 0Hz
from 50Hz in 5 seconds.
The deceleration rate could be extended by the drive to prevent over voltage (OU)
NOTE
trips if the load inertia is too high for the programmed deceleration rate, if one of
the standard ramp modes is selected - parameter 30.
Although the acceleration and deceleration rates can be set to 0.0, there is a
NOTE
minimum ramp rate within the software of 0.1s/100Hz.
No. Function
Speed reference
05
select
The setting of parameter 05 will select the type of speed reference input and also the
function of the digital inputs on terminal 12 and 13.
Parameter 05 settings:
• A1.A2 - Analog voltage input on terminal 2 and analog current input on terminal 5
selected by terminal 12. Jog selected by terminal 13
• A1.Pr - Analog voltage input on terminal 2 and 3 preset speeds selected by
terminals 12 and 13
• A2.Pr - Analog current input on terminal 5 and 3 preset speeds selected by
terminals 12 and 13
• Pr - 4 Preset speeds selected by terminals 12 and 13
• PAd - keypad control
