 |
What wattage power supply is required? |
 |
|
 |
When selecting a power supply, its wattage has to be large enough for the peak current. Usually, a single axis motor requires a Muscle 150W power supply. When using multiple axes, please select a power supply that wattage is large enough for the all motors’ peak current. |
|
What is the maximum cable length? |
|
|
|
In a normal operating environment, the motor cable that comes with the motor is recommended to be shorter than 40cm, and RS-232C cable to be shorter than 2M. |
|
What are required for networking multiple Cool Muscles? |
|
|
|
Each axis requires one network card ( The first axis/Master Set, The second and later axes/Slave Sets ). Also the same number of straight cables as the number of axes are required. For example, when 3 Cool Muscles are in the daisy-chain network, one master card for the first axis, two network cards for the 2nd and the 3rd axis and 3 straight cables are required. Please refer to the User’s Guide for details. |
|
Does the power need to be supplied to each motor in the daisy-chain network? |
|
|
|
The power can be supplied either "to each motor separately" or "at the same time via the communication cable in the network". However it is recommended that power is supplied to each motor to obtain more stable power. |
|
Is there any delay between Cool Muscles in the daisy-chain network? |
|
|
|
There is a slight delay. Even when simple commands are used, theoretically there will be a delay of approximately 4 msec. Please note that the delay time depends on the host controller and/or operating condition. |
|
What communication method does Cool Muscle support besides RS-232C? |
|
|
|
Cool Muscle supports only RS-232C. When another method is required, a communication signal level converter will be required. |
|
There is no communication between a PC and Cool Muscle. |
|
|
|
1. Please supply the power to Cool Muscle when a PC is running. 2. Please check the baud rate on a PC. Please refer to the User’s Guide for details. |
|
How can the rotational speed be calculated from Cool Muscle speed value? |
|
|
|
The rotation speed can be calculated from the Cool Muscle’s resolution
and Speed value. RPM = S x Speed unit set by K37 (100pps/10pps) x 60 / resolution The speed calculation function is available in COOLWORKS LITE to automatically calculate the rotation speed. |
|
How can the acceleration be calculated? |
|
|
|
Acceleration value is the speed that the motor reaches in a second
after its revolution starts. A x 1000(Kpps^2) x 60 / resolution = speed a second after The motor accelerates to reach this speed in a second but does not exceed the speed set by S. |
|
What is the maximum number of program banks that can be stored in Cool Muscle? |
|
|
|
The maximum number of program bank is 30 and the total step is up to 500. |
|
A program bank can not be executed. |
|
|
|
The definition of a program bank must begin with " B1.1". Please confirm if the program banks have been properly downloaded to Cool Muscle by entering the query command “?1000.1”. |
|
How can an alarm be reset? |
|
|
|
Since a motor is free when an alarm is occurred, the enable motor
command " ( " will reset the alarm and enable the motor. An alarm can be reset by an input signal. The input functions can be assigned by either 1: Alarm Reset/Pause or 2:Enable the Motor. Please refer to the User’s Guide for details. |
|
How can the motor be enabled from motor free status? |
|
|
|
Use the enable motor command " ( " to enable motor. When using the input functions, a motor can be enabled by a input signal to enable motor. The input functions can be assigned by either 1:Alarm Reset/Pause or 2:Enable Motor. Please refer to the User’s Guide for more information. |
