Elmo SimplIQ Series - JV- Jogging Velocity

JV- Jogging Velocity
Purpose:
Sets the motor speed. In speed control mode (UM=2), the JV parameter specifies the
software speed command. In un-profiled mode (PM=0), the speed command is set to JV
immediately. In profiled mode (PM=1), the speed command is gradually changed to JV,
according to the AC, DC and SF parameters.
In the position control modes (UM=4, 5), the JV setting defines a constant speed software
command. The value of JV defines the speed of the motion.
The parameters AC, DC and SF determine the acceleration limits for reaching final speed.
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 according to the last modulo setting, but
the speed will remain steady.
Notes:
 Jog mode is recommended for homing procedures, because it does not require
information about 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.
