Instruction Manual PSx3xxC
28
CANopen state is ‘preoperational’, bit 3 of the control word is without meaning. The
continuous manual run is always enabled under these conditions.
The idle period before the drive switches into manual run is specified in SDO #2023.
In manual run the drive runs maximum to the specified limit switch position (SDO
#2016 or #2017).
If during an jog run both external keys are pressed, the run is aborted immediately. A
new jog run is only possible if both keys are released.
To prepare the function of the external keys, the corresponding key contact (pin 2 or 3
of the 4-pin plug) must be connected with +24V (pin 1). If the key signal is generated
by a voltage source which is galvanically separated from the internal voltage source
of the drive, GND (pin 4) must be connected.
Jog runs without external keys:
Jog
runs are also possible without external keys. For this purpose bit 8 (‘jog run to
larger value
s’) and bit 9 (‘jog run to smaller values’) are provided, these bits simulate
the pressing of the corresponding external keys.
Requirements:
- Bits 4 and 5 of the control word have to be reset.
AND
- SDO #204C must be set to 0 or the CANopen
state is not ‘preoperational’.
h) Devices with optional holding brake
The device models PSx30xC-14, PSx31xC-14, PSx32xC and PSx33xC can be
supplied with an optional holding brake. This brake prevents the output shaft from
turning when the power supply to the motor is removed, or, if the motor holding torque
is too low, to a maximum of the level of the nominal torque. A small degree of rotation
always occurs at the output, i.e. the brake cannot be used to hold the drive at a
defined position (for this purpose where appropriate the holding torque might be
increased with the help of SDO #202B and SDO #2042).
To release the brake when a run command is transmitted, these devices first wait for
a short time (by default 0.15 sec before beginning the run, SDO #2044) and then run
a few increments against the actual direction of movement (number of increments:
SDO #2048). The brake is closing at the end of every run (by default 1 sec after the
end of the run, SDO #2045). The advantage of this feature is, that in case of many
subsequent runs the brake has not to be released anew each time.
To adjust the position of the drive manually, it is first necessary to remove the rubber-
plug in the top cover (see drawings at the end of these instructions). Then release the
brake by pressing down and simultaneously turning using a hex wrench NW3
(PSx31xC and PSx33xC) or NW4 (PSx30xC and PSx32xC).
i) Devices with optional friction brake
The device model PSE34xxC can be supplied with an optional friction brake. This
brake prevents the output shaft from turning when the power supply to the motor is
removed, or, if the motor holding torque is too low.
A run command is not approached immediately but only after a short idle period to
tighten the brake.
