Motor control

Jog mode
Jog mode is used, for example, to set up a machine in manual
control mode. To use jog mode, one of the digital inputs (1 to 5)
must be activated with the JOG signal (= 06) with PNU C001 to
C005. When a start signal is then applied to the FWD or REV input,
a relatively low frequency without acceleration ramp is applied to
the motor.
You can set this jog frequency with PNU A038. Make sure that the
frequency is not too high, as it is applied directly to the motor
without an acceleration ramp. Excessively high jog frequencies can
cause a fault signal. It is best to use a frequency below 5 Hz.
By default (PNU A002 = 01) the position of microswitch TM/PRG
has no function.
The value of PNU A039 determines how the motor is slowed.
The jogging frequency can be read off with an optional keypad.
X To do this, enter the value 02 in PNU A002.
X Set microswitch TM/PRG to its PRG position.
X Activate the digital input configured as JOG.
Use the START and STOP keys to start and stop the motor
respectively.
h
Operation in jog mode is not possible when the jogging
frequency set under PNU A038 is less than the start
frequency set under PNU b082 (a section “Increased
starting frequency”, page 66).
h
Jog mode can be activated only when the frequency
inverter is in the Stop state.
Caution!
Make sure that the motor has stopped before using jog
mode.
h
Jog mode is started only through the active JOG input, not
through the keypad.
