When operating and stopping the product using a programmable controller, or when using source logic, refer to p.15. Pin No.1 +24 V 24 VDC±10% Pin No.2 0 V (GND)
Connection 5.5 Connection example for I/O signals and programmable controller Figure viewed from the lower face Set the input logic to the sink logic side or source logic side in accordance with of the speed controller the programmable controller used with the speed controller. It is set using the SW1 as shown in the figure. Sink logic (SINK) is set at the time of shipment.
Operation 6 Operation This chapter explains how to operate the motor and speed controller. Installing the speed controller Connecting the motor p.12 Connecting the control Connecting the AC power DC power supply and I/O signals supply and capacitor p.13 p.11 6.1 Power ON Turn on the power after completing the connection.
Operation 6.2 Starting, stopping When either the FWD input or REV input is turned ON after setting the rotation speed, the motor will rotate at the specified speed. If the signal (FWD input or REV input) which has been turned ON is turned OFF while the motor rotates, the motor will decelerate to a stop according to the specified deceleration time.
Operation Setting method using the operation panel The rotation speed can be set while rotating the motor, and it can also be set in the motor standstill state. This section explains how to set the rotation speed while rotating the motor as an example. Example: Set the rotation speed to 1000 r/min from 0 r/min Setting method Panel display...
Operation 6.4 Setting the acceleration time and deceleration time The acceleration time and deceleration time can be adjusted to prevent the load from receiving a shock upon starting, stopping, or changing in speed. Refer to p.26 for how to set each operation data using the operation panel. Setting range: 0 to 15.0 seconds The actual acceleration time and deceleration time against the setting vary depending on the inertial load, frictional load, set rotation speed or motor output power.
Operation 6.6 Timing chart This is an example of a timing chart for a basic operation. Example: 1200 r/min is set in the operation data No.0, and 100 r/min is set in the operation data No.1. Run/ Speed change/ Run/ Instantaneous Run/ Stop Instantaneous stop...
Operation 6.8 Operating at two or more speeds (multi-speed operation) The multi-speed operation can be performed by setting the rotation speed Low speed and switching the ON-OFF status of the M0 and M1 inputs. High speed Data setting method (example: rotation speed) Power ON Panel display Rotation speed: 0 r/min (Initial value) Press...
Operation 6.9 Adjusting the rotation speed of two or more motors by a single setting device (multi-motor control) Two or more motors can be operated at the same speed using a single variable resistor or external DC voltage. Set the "external speed command input" parameter to "ON (enable)," and turn the M0 input and M1 input OFF. Refer to p.27 for parameter.
