Optionally, the RollerDrive EC100 is also available with a failsafe brake (then
called EC100B), which is designed to hold the RollerDrive in position in case of a
power shut down, mainly at declines. The brake shall be used as holding brake
only and not as a dynamic brake (e.g. not for deceleration or positioning).
Recommended break leads connection:
• Green lead with red stripes: 24 VDC
• Green lead with blue stripes: GND
The fail save brake is not sensitive to electrical polarity, so it can be connected bi
polar; for clearness it is recommended to connect them as stated above.
