Note

R–W = Read–write parameter RO = Read-only parameter

Selection of Pr0, Pr1, Pr2, and Pr3 is controlled by Pr17, which receives its coding from the values of Pr18, Pr19 and Pr20, as selected by b16 and

–3000 to 3000 RPM when Pr99 = 200 to 3000

If the DC bus voltage falls below the value of Pr5,the Drive stops automatically.(See Auto Stop function )Permits the user to apply a correction to an offset in the analog speed reference which would cause slow rotation of the motor when zero speed is intended.resonance in the mechanical transmission, or by high inertia of the driven load.

programmed in Pr27 within which it is assumed that the motor shaft is correctly orientated when Speed in RPM adopted during shaft orientation. See Pr27.Enter the value for the motor.Refer also to Pr57, b42 and b96.

If the motor exceeds this limit, an over-speed trip occurs . See b87.When Pr68 = 0, pulses per revolution = 256When Pr68 = 1, pulses per revolution = 512When Pr68 = 2, pulses per revolution = 1024

When Pr68 = 3, pulses per revolution = 2048

Note

When Pr68 is set at 3, the maximum permissible speed is 3000 RPM Pr70. For each resulting pulse, the motor shaft will rotate Pr70/16384 part of a revolution. Refer also When the Drive is set up to operate in position control with a frequency input signal, Pr71 is used to add integral gain to eliminate steady-state

position error.

Defines the type of signal given by the At-speed status parameter b42.

When b96 is set at 0, absolute is selected.When b96 is set at 1, relative is selected.

When b96 is set at 1 (relative) the At-speed status held in b42 is related to the Speed Reference input,so that b42 = 1 (At speed) when the motor speed is between the two limits, as follows:

Greater than [Speed reference] – Pr56Less than [Speed reference] + Pr57

When b96 is set at 0 (Absolute) the At-speed

status held in b42 responds to the absolute values set in Pr56 and Pr57, so that b42 = 1 (At speed)when the motor speed speed is between the two limits, as follows:

Greater than Pr56Less than Pr57

Refer also to Pr56, Pr57 and b42.

Saves new parameter values in the EEPROM . The display shows SAVE while parameters are being saved . b99 is related to b1 and b5.When b99 is set at 0, no saving occurs.When b99 is set at 1, parameters are saved.
