JV- Jogging Velocity

Purpose:
Sets the motor target speed for speed and position control (UM=2,3,4,5). After the next
BG, the speed command is gradually changed to JV, according to the AC, DC and SF
parameters.

In position-jogging mode (JV), and if the position feedback sensor is set to modulo
counting (refer to

XM[N]

and

YM[N]

), a position-controlled motor can rotate forever.

The position reading will jump each modulo count crossing, but the speed will remain
steady.

Notes:

Jog mode is recommended for homing procedures, because it does not require

information about the starting position or destination.

In position mode (UM=4, 5), a jogging command is under position control. The

JV parameter determines the rate at which the position-command changes.

In stepper mode (UM=3), JV determines the rate at which the electric angle

command changes.

In position control mode (UM=3, 4, 5), JV not only sets the speed of motion but it

also states that the next motion will be a constant speed jog.

For all relevant modes (UM=2, 4, 5), the value of JV must be set between VL[2]

and VH[2]. Setting JV out of this range will invoke an “Out of limit” error code.
