INSTALLATION & USER’S MANUAL
5.10.1.1.4 Homing
Switch
This handler function is used to configure the input as a homing switch. The homing switch is used when certain
homing methods are configured. The default operation is that the homing switch is inactive when the input is
cleared, and active when the input is set.
5.10.1.1.5 Quickstop
This handler function is used to configure the input as a quickstop input. The default operation is to quickstop the
drive if the input is set, i.e. decelerates at a programmable rate. The drive can be set up to disable or remain
enabled once the quick stop is complete by setting bit 0 of
quickstop_mode
(1013). If set to 1 then the drive will
disable, if set to 0 then the drive will remain enabled.
If the drive is configured to disable on a quick stop by setting bit 0 to 1, the brake is applied (if configured to do so)
when the velocity decreases below a programmable level set by
standby_velocity
(1138). The drive will then
disable a programmable time after the brake is applied set by
brake_lock_to_disable_timeout
(1004).
If the velocity does not decrease below
standby_velocity
within a programmable time
velocity_rampdown_time_limit
(1143) then the drive will disable and the brake applied (if configured to do so).
The operation of the brake under a quick stop with disable can be configured to either apply or remain released
using the
brake_control
parameter as described in the Brake Release Switch section.
5.10.1.1.6
Automatic / Manual Mode
This handler function is used to select between automatic (where normal limits apply) and manual mode (reduced
power mode). The default operation is to be in manual mode if the input is cleared (i.e. no current flows), and to
be in automatic mode if the input is set. In manual mode, the drive operates with Manual mode torque limit and
Manual mode velocity limit. The percentage of max torque and max velocity with which the drives operates is set
using
manual_mode_limit
(1133) in %. This parameter sets the maximum available torque to a percentage of
current
_
maximum_physical
(1124) and the maximum velocity to a percentage of
velocity_maximum
(1085).
5.10.1.1.7 Controlled
Disable
This handler function is the same as the quickstop handler listed above, but configured to always disable when
quickstop is complete.
5.10.1.1.8 Re-Boot
When the input is true this function will force the drive to restart.
CAUTION:- the user can program the MANUAL_MODE torque and velocity limits to be higher
than the same limits in the AUTOMATIC_MODE. The user should ensure that the correct limits
are set-up in the DS2110 software, so that inadvertently limits are not swapped or used
incorrectly in either MANUAL or AUTOMATIC states.
