7.2.5 Examples of Analog – Speed Mode
In the analog – speed mode, follow the steps below to set a driver:
Step 1: Confirm whether it is necessary to enable the driver 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 the driver does not
require enabling through external digital input ports, you can disable the enabling function of external digital
input ports by referring to Table 6-13 of Example 6-3, and enable the auto power-on function of 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 limit switches are unavailable,
please disable the function of limit switches by referring to Example 6-4.
Step 3: Confirm the mode switching positions and operation modes by referring to the settings in Example 6-5.
The factory default settings are as follows: When no signal is inputted to DIN3, the driver operates in the “-4”
mode (d3.16 = -4); when signal is inputted to DIN3, the driver operates in the “-3” mode (d3.17 = -3). If the
driver is required to operate in the speed mode after being powered on, set d3.16 to -3 or 3.
Step 4: After configuring functions on digital input ports, select the analog – speed channel, and set
parameters such as analog – speed factors, dead zone, offset and filtering.
Step 5: Save parameters.
Example 7-3: Analog – speed mode (without setting the dead zone voltage
and offset voltage)
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 “-3” when no signal is inputted, and is “3” when signal is inputted).
Limit switches are unavailable. The voltage 10V corresponds to the rated rotation speed of 3000 rpm, and
-10V corresponds to the rated rotation speed of -3000 rpm. Select analog channel 1 (AIN1) to control the
speed.
