If DIN is defined as “Gain Switch” function,then the parameter “PI_Switch” will disable.
Parameter “PI_Point”(60F92808) is used to display the current gain.
Auto-tuning can only be used to set Gain 0.
Vc_Loop_BW and Pc_Loop_BW are only corresponding to Gain 0.Other Gain needs to set by manual.
“PI_Switch” is used to switch Gain 0 and Gain 1.In mode -4,1 and 3,it will use Gain 1 when “Position reached”
signal is valid,and use Gain 0 when “Position reached” signal is invalid.
7.1.3 Examples of Pulse Control Mode
In the pulse control mode, follow the steps below to configure a driver:
Step 1: Confirm whether the functions of the driver require enabling through external digital input ports. To
enable the driver through external digital input ports, see Table 6-12 in Example 6-3 for settings. If it is not
necessary to enable the driver through external digital input ports, you can disable the enabling control
function of external digital input ports by referring to Table 6-13 of Example 6-3, and enable the driver by
setting its internal parameters.
Step 2: Confirm whether limit switches are required. By default, the driver operates in the limit status after
being powered on. In this case, the numeric display has limit status display. If there is no limit switches,
please disable the function of limit switches by referring to Example 6-4.
Step 3: Confirm mode switching bits and operation modes by referring to the settings in Example 6-5. The
factory default settings of the driver are as follows: When no signal is inputted on DIN3, the driver operates in
the “-4” mode (pulse control mode).
Step 4: After function configuration on digital input ports, it is required to set parameters such as pulse modes
and electronic gear ratio.
Step 5: Save parameters.
Example 7-1: Pulse control mode “-4” – enable the driver through external
digital input
Requirement: DIN1 is used for enabling the driver, DIN2 is used for error resetting, and DIN3 controls the
operation modes of the driver (the mode is “-4” when no signal is inputted, and the mode is “-3” when signal is
inputted). Limit switches are unavailable. The pulse form is pulse/direction, and the electronic rear ratio is 2:1.
Table 7-7 describes the setup method.
