6.3.20 Enable switch function
If set to “Run”, input IN_A3 (P3.29) acts as an “Enable” input when the user program
is not executing. If the user program is executing, the function will always be “Inhibit”
regardless of the setting. This parameter is needed so the drive can be Enabled/
Disabled without running a user’s program.
6.3.21 User Units
This parameter sets up the relationship between User Units and motor revolutions.
From here you can determine how many User Units there is in one motor revolution.
This parameter allows the user to scale motion moves to represent a desired unit of
measure, (inches, meters, in/sec, meters/sec, etc).
For example:
A linear actuator allows a displacement of 2.5” with every revolution of the motor’s
shaft.
User Units = Revolutions / Unit
User Units = 1 Revolutions / 2.5 Inches
User Units = 1 / 2.5 Revolutions / inch
User Units = 0.4 Revolutions / inch
6.4 Communication
6.4.1 IP Setup
This action button opens dialog for TCP/IP related parameters setup.
6.4.2 RS-485 configuration
This parameter sets how the optional RS485 interface will function. The RS485
interface can be configured for normal operation (programming and diagnostics using
MotionView software) or as a Modbus RTU slave. See section 5.4 for details on
communication interfaces.
6.4.3 Modbus baud rate
This parameter sets the baud rate for RS485 interface in Modbus RTU mode. When
the drive is operating in normal mode the baud rate is set to the same setting as the
RS232 interface.
6.4.4 Modbus reply delay
This parameter sets the time delay between the drives reply to the Modbus RTU
master. This delay is needed for some types of Modbus masters to function correctly.
6.5 Analog I/O Group
6.5.1 Analog output
The PositionServo 940 has one analog output with 10-bit resolution on P3.23. The
signal is scaled to ± 10V. The analog output can be assigned to following functions:
• Not Assigned
• Phase current RMS
• Phase current Peak
• Motor Velocity
• Phase U current
• Phase V current
• Phase W current
• Iq current (Torque component)
• Id current (Direct component)
