The power-up mode of the drive. PM determines how the drive is configured for serial communications
at power-up. For example, for SCL applications set PM=2 or PM=5. The power-up mode can also be set
when configuring the drive with Quick Tuner or ST Configurator. PM2 (Q / SCL) is the same as PM7 (Q
Program Mode), except the program is not automatically executed at power up.

There are two Jog modes available:
JM 1: Jog Mode 1 uses position control that moves the target position which causes the servo to move
at the set velocity. Jog Mode 1 will cause the servo motor to always move the same distance over time. A
drawback is that the servo can fault if the position error during the move exceeds the value set by the PF
(Position Fault) command.
JM 2: uses velocity control that applies torque to the motor to maintain velocity. This method functions
better with high inertia loads because it ignores the value set by the PF (Position Fault) command. It also
allows the drive to function in a “torque-limited velocity” mode or a “velocity-limited torque” mode. Jog
Mode 2 also uses a different set of control parameters, VI and VP, for “tuning” the velocity mode.
