Jog
When the drive is not running, pressing the HIM’s Jog soft button or a
programmed Jog digital input function or by Logic Command (sent over a
communication network) causes the drive to jog at a separately programmed jog
reference. This jog speed reference value is entered in P556 [ Jog Speed 1] or P557
[ Jog Speed 2].
Scaling of an Analog Speed Reference
Refer to Analog Inputs on page 105 .
Polarity
The polarity configuration can be selected as unipolar, bipolar, or reverse
disabled via P308 [Direction Mode]. When in Unipolar mode, the sign of the
speed reference value (and therefore direction of motor rotation) is determined
by P879 [Drive Logic Rslt] Bit 4 “Forward” and Bit 5 “Reverse.” When in Bipolar
mode, the sign of the speed reference value determines the direction of motor
rotation. When in Reverse Disable mode, negative speed reference values are
rejected and a zero speed value is used in their place.
