When the set bandwidth becomes smaller, the
motor responds slower. The formula is
F=Speed_Fb_N*20+100.
For example, to set the filter bandwidth to "F = 500
Hz‖, the parameter should be set to 20.
Proportional gain of velocity loop Kvp: If the proportional gain of the velocity loop increases, the responsive
bandwidth of the velocity loop also increases. The bandwidth of the velocity loop is directly proportional to the
speed of response. Motor noise also increases when the velocity loop gain increases. If the gain is too great,
system oscillation may occur.
Integral gain of velocity loop Kvi: If the integral gain of the velocity loop increases, the low-frequency intensity
is improved, and the time for steady state adjustment is reduced; however, if the integral gain is too great,
system oscillation may occur.
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.
