may be optionally enabled with Pr 6.13 ). The speed reference is defined by Pr 1.17 . This is a read only parameter that can only be adjusted in status
mode by pressing the Up or Down keys. If keypad control mode is selected, then pressing the Up or Down keys in status mode will cause the drive to
automatically display the keypad reference and adjust it in the relevant direction. This can be done whether the drive is disabled or running. If the Up
or Down keys are held the rate of change of keypad reference increases with time. The units used for to display the keypad reference for different
modes are given below.
See also Pr 1.51 on page 33 (Power-up keypad control mode reference).
Pr 1.18 defines the coarse part of reference (either positive or negative) with a resolution of 0.1 rpm and Pr 1.19 defines the fine part of the reference
(always positive) with a resolution of 0.001 rpm. The final reference is given by Pr 1.18 + Pr 1.19. Therefore Pr 1.19 increases positive references
away from zero, and decreases negative references towards zero.
parameters, this bit is provided to prevent the drive reading the parameters while the reference is being updated. Instead, the drive uses the value
stored in memory preventing the possibility of data skew.
