Pr.36, Pr.37 – Reference Frequency: Upper / Lower limit

Pr.36 Reference Frequency Upper Limit

Factory Setting d400.0 Hz

Units 0.1 Hz

Parameter Value d0.1 - d400.0 Hz

This parameter programs the upper limit of the reference frequency in 0.1 Hz
increments.

Pr.37 Reference Frequency Lower Limit

Factory Setting d0.0 Hz

Units 0.1 Hz

Parameter Value d0.1 - d400.0 Hz

Determines the lower limit of the reference frequency in 0.1 Hz increments.

Application Notes:

1. Parameters 36, 37 are provided to prevent damage to the AC motor and applicable
machinery. Under certain conditions a motor can overheat and/or machinery can be
damaged at excessively high speeds.
2. The lower limit for AC drive operation is determined by the greater value of Pr.08

(Minimum Output Frequency) and Pr.37 (Reference Frequency Lower Limit). The
upper limit for AC drive operation is determined by the lesser value of Pr.03

(Maximum Output Frequency and Pr.36 Reference Frequency Upper Limit).

Pr.38 Multi-Function Input Terminals (M0, M1)

Factory Setting d00

Units None

Settings d00 - d02

Pr.39 Multi-Function Input Terminals (M2)

Factory Setting d05

Units None
