Running The Motor In Jog Mode (Jog Function) - Siemens SINAMICS G120 CU230P-2 HVAC Operating Instructions Manual

Functions
7.4 Setpoint sources
Example: Selecting two fixed speed setpoints using digital input 2 and digital input 3
The motor is to run at two different speeds:
● The motor is switched on with digital input 0
● When digital input 2 is selected, the motor is to run at a speed of 300 rpm.
● When digital input 3 is selected, the motor is to accelerate to a speed of 2000 rpm.
● When digital input 1 is selected, the motor should go into reverse

Running the motor in jog mode (JOG function)

Using the "jog" function (JOG function), you can switch the motor on and off using a control
command or the operator panel. The speed to which the motor accelerates for "Jog" can be
set.
The motor must be switched-off before you issue the "jog" control command. "Jog" has no
effect when the motor is switched on.
The "Jog" function is typically used to manually switch-on a motor after switching over from
automatic to manual operation.
Setting jogging
The "Jog" function has two different speed setpoints, e.g. for motor counter-clockwise
rotation and clockwise rotation.
With an operator panel, you can always select the "Jog" function. If you wish to use
additional digital inputs as control commands, you must interconnect the particular signal
source with a digital input.
